If you have a rectangle and the length of only one side is given,how do you find the perimeter. The video shows how the diagonal creates a right triangle. This right triangle can be used to find the other side of the triangle, and then the perimeter.
Need a little bit of help figuring out how to solve word problems involving the perimeter of a rectangle? See how it's done with this free video math lesson. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).
One thing that you will need to know in order to pass Geometry is how to find the perimeter of a parallelogram. Parallelograms are quadrilaterals with two pairs of parallel sides. It is not difficult to find their perimeter, but you will need to know a few steps. Check out this video for tips on how to do this in your math class and ace that big test.
Two dimensional objects are measured in terms of perimeter and areas. A perimeter of a two dimensional object is the distance around that object. If you want to find the perimeter of an object, all you need to do is add up each one of the lengths of sides of that object. If you have a small figure like triangle, first compute the length of the three sides. Now adding these three sides gives you the perimeter of the triangle. A larger or more complicated shape might have more number of sides. ...
This video shows you how to easily find the perimeter of a rectangle or even a square. The perimeter is the total length of the path that surrounds the area of a rectangle or a square (in this case). For a rectangle, the perimeter length is equal to 2L+2W, where L is the length and W is the width. For a square, the perimeter length is equal to 4L, where L is the length or simply one side. e.g.: L=3, W=2 => P(Perimeter) = 10. That's it! Good Luck!
In this video tutorial the author shows how to find the perimeter and area of a complex figure. He shows that a complex figure can be subdivided into standard geometric figures. In the current example he divides the complex figure into a rectangle and a triangle. Now he computes the perimeter by adding the three sides of the rectangle and the two sides of the triangle. Similarly he computes the individual areas of the rectangle and the triangle and finally adds then up to find the area of the...
This video starts out with a basic view of a rectangle and its dimensions. The base is 7 inches while the sides are 4 inches. It then displays the formula for finding the perimeter of the rectangle which is the addition of both bases and both sides. After the substitution of the values into the formula you can quickly come up with the perimeter. Then moving on the area, the formula is the base multiplied by the side. In this case, the base being 7 inches and the side being 4 inches you come o...
For people who are learning geometry and would like to be able to find the perimeter of a rectangle, this video provides and quick and simple tutorial which provides the formula as well as a good example. The formula for finding the perimeter of a rectangle is simple the sum of all sides, or l+l+w+w, where l is the length and w is the width of the rectangle. After attaining the values of the length and width of the rectangle, you can simply plug in the values to this equation in order to find...
When you are figuring the area of a square, you only need to know the height and width of the shape. Once you know the height and width, multiply them to get the area of the square. To find the perimeter of the square, add all four sides together. To find the area of a triangle, multiply together two of the sides (not the hypotenuse) and then multiply that figure by 1/2. To find the perimeter of the triangle, add all three sides together.

It's no secret, artists are broke. That's why they're referred to as "starving artists". One day these artists will achieve unimaginable success, but for most of their lives, they'll be struggling to survive… struggling to keep their vision alive. That's why they need to work cheap. And that's why they stretch their own canvases, not buy pre-made ones or have the hobby shop do it. If you’re a starving artist, save a few bucks, hone your carpentry skills, and stretch your own canvas.

Charles M., an attorney and bonsai cultivator, demonstrates how to transfer a field grown Japanese Black Pine that is ready for training. A 5-gallong nursery specimen was purchased and planted in the ground with a bonsai compound soil to keep its roots close and compact during trunk thickening. The tree was allowed to grow for three years, with the main foliage under four feet, but with two “sacrifice” branches allowed to shoot out without trimming. One sacrifice branch at the top of the tree...
Area of a triangle can be calculated when you have the length of its base and height. In this case the area is 1/2 times the base and its height. If you do not know the height of the triangle but know the lengths of all the sides of the triangle then you can calculate its area using the Herons formula. First to use it you need to computer the semi perimeter of the triangle S, which is S = (a + b + c)/2, where a, b, c are the lengths of the sides of the triangle. Now the area of the triangle i...
Here in this video we are about to see how windshield wiper fluid is being changed. Open the car and look for the symbol which is on the cap of the reservoir. Remove the cap. Now pour the wiper fluid into the reservoir. The wiper fluid used varies from deicer to detergent. People tend to use the water which might turn bad once the temperature drops below a certain degree. So the water freezes ultimately the system stops making it a useless one. So the fluid is filled till it reaches the top o...

This video shows how to calculate the circumference of a given circle. The video first describes the circumference or perimeter of a circle as the distance around the outside of a circle. To find the circumference we need either the radius or the diameter of the circle. When you know the diameter of the circle, the formula to find the circumference denoted by 'C' is 'pi' times the diameter, where 'd' is the diameter and 'pi' is a constant, the approximate value being 3.14. And when you are gi...

This video from Your Teacher is one of a range of math solutions. (which is the measurement from the center to the edge when drawn in a straight line) and also the area of the circle, is the amount of total space within its perimeter. The circumference of this circle is 20 pi. The circumference is 2 pi r. So 20 pi is 2 pi r. Which factors down to show that 10 is the radius (10=r). The area is pi r squared. As we know the radius is 10, we can work out the area - 100 pi.
