15=2(s+(s/2))

15=2s+s

15=3s

s=5in

A=s^2

With a little trial and error, I figured that the dimensions of the rectangle are 2.5 by 5

That means that the original square has 5 inches on each side.

Take it from there.

15x4=60 or 15x5=75.

I'm not sure?

CeCe -- please do not post answers when you don't know! You're just confusing other students.
