d = sqrt( ss + ss )
dd = ss + ss
dd = 2ss
ss = dd/2
s = sqrt( dd/2 )
s = sqrt( (15^2)/2 )
s = 10.606601717798213

answer:
p = 2s + 2s
p = 42.426 m
a = ss
a = 112.5 sq.m

If we can find the side length of the square we can
find the area and perimeter.
Let s = the side length of the square.

The area = = 225/2 = 112.5 sqft
The perimeter = ft
