Question

Carla is framing in a square sand box in her back yard. She has set aside an area of 24 square feet for the sandbox. The sandbox is to be 1.5 times longer than it is wide. What is the length of the longer side for the sandbox?​

Answer 1

A=lw

Let l=1.5w

24 = (1.5w)w
24/1.5=w^2
16=w^2
4=w

l=1.5(4) = 6

Width is 4 feet and length is 6 feet
