Question

Chloe knows that her kitchen is a rectangle with an area of 168 square feet. If the length of her kitchen is 12 feet, what is its width? What is its perimeter? Show all your work.

Answer 1

So the area formula for a rectangle is length x width.
We are given the length: 12 and the area so you can plug in the values and you get: 12 x width= 168, if you solve for the width you get, 14 feet.
To find the perimeter you use the formula: 2(length) + 2(width)
So plug in the values and you get 2(12)+2(14)= 52 feet
