Example Question #21 : Geometry
A farmer wants to build a rectangular fence to enclose a yard. If the yard is square, how many feet of fence will he need?
The area of a square is . Since our area is ,
.
Take the square root of both sides.
The perimeter of a square is the sum of all four sides. Since all sides are equal, we can say that, for a square, the formula for a perimter would be .
Plug in what we just found:

The perimeter of a rectangle is the sum of the length of each of the four sides.
Since
substitute each in:
Example Question #1 : How To Find The Perimeter Of A Rectangle In Pre Algebra
Find the perimeter of a rectangle with length 8 inches and width 10 inches.
To find perimeter, add up all the sides. In a rectangle, there are 2 sets of identical sides so you can multiply the length by 2 and the width by 2 and combine them to get 36 inches.
Example Question #2 : How To Find The Perimeter Of A Rectangle In Pre Algebra
Find the perimeter of a rectangle with a length of 20 inches and a width of 12 inches.
Add up all of the sides of the rectangle to get 64 inches.
Example Question #4 : How To Find The Perimeter Of A Rectangle In Pre Algebra
What is the perimeter of a rectangle with a base of and a height of ?
To find the perimeter of a rectangle you must find the sum of all of the side lengths.
To do this we plug the base and height into the equation
With a base of and a height of our equation would look like
Multiply and add the numbers together
The answer is .
