This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.

√400 = 20

One side's measurements is 20 in

hope this helps

It's a square, so

A = b * h or l²

l = √A

-------------------------------

l = √400

l = 20 in
