What is your question?
.
For a square:
Area =(side)^2
361in%5E2=%28side%29%5E2
sqrt%28361in%5E2%29=sqrt%28side%5E2%29
19in=side
.
The sides of the square are 19 inches
Subtract 2 inches from one side and add to adjacent side:
Dimensions of the rectangle were
(19-2) x (19+2) = 17 x 21
The rectangle was 17 in by 21 in.
