Question

Elise built a rectangular vegetable garden that is 9 feet long and has an area of 72 square feet.

Answer 1

The answer is 34 you would divide 9 from 72 and get 8 then 8*2 plus 9*2

Answer 2

The area is found by multiplying the Length x the Width.  9 x ?=72 
9x8=72   Now you know the length of each side. 9+9+8+8 =34 
Adding the lengths of each side will give you the perimeter. 34 is the answer.
