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.
