a square's sides are all the same.

Root the area to get the measurement of one side

√20.25 = 4.5

4.5 in. is the measurement of one side.

Answer 2

In order to find the area of a square you simply have to square one side. Therefore, in order to go backwards to find the side length you have to square root the area. If you square root 20.25 you get 4.5 which is the length of one side. Hope this helps :)
