Example Question #11 : How To Find The Perimeter Of A Rectangle In Pre Algebra
A rectangle has a width of feet and a length of
feet. What is the perimeter of the rectangle?
feet
feet
square feet
feet
square feet
feet
Recall that perimeter is the sum of all of the sides of a shape. Thus, we are adding up all sides of the rectangle. A rectangle has two sides that are the length and two sides that are the width. Thus,
feet.
Perimeter is a measure of length, and not area (or square feet), so our units are just feet.
Example Question #12 : How To Find The Perimeter Of A Rectangle In Pre Algebra
Rectangle ABCD is subdivided into two identical square regions. If the area of each square is , what is the perimeter of ABCD ?
Given that the area of each square is , the side length of each square is
. To find the perimeter of the entire shape, one must add up the lenghts of the sides of the shape. Thus the sides of the rectangle are each
, and the bases are
(because the squares are connected). Adding them all together gives us
.
