Answer:
13.15 in
Explanation:
We know that to get area for a square is
Side x side = side ^2
(normally we would put an algebra for it, but i just write i like this so that it is easier to understand)
OK therfore I can say
Area = side ^2
173 = side ^2
When u bring a square over, it becomes square root
So...
Square root 173 = side
Side = 13.15in
