Hello!
To find the side length of a square with the diagonal you use the equation
[tex]a = \sqrt{2} \frac{d}{2} [/tex]
a is side length
d is diagonal length
Put in the values you know
[tex]a = \sqrt{2} * \frac{32}{2} [/tex]
Divide
[tex]a = \sqrt{2} * 16[/tex]
Multiply
a = 22.6
All the sides are 22.6 feet
Add all the sides
22.6 + 22.6 + 22.6 + 22.6 = 90.4
The answer is 90.4
Hope this helps!
