Length = 2*width - 5
perimeter = 2(length + width)
89 = 2(2width - 5 + width)
89 = 6 width - 10
6 width = 99
width = 99/6 = 16.5 feet
length = 2*16.5 - 5 = 28 feet

Answer:
i am not good in maths sorry the answer is 6075
The area of one face would he h^2.
There are 6 faces, so the total surface area would be h^2 x 6
Replace total surface area with 2.16, so you now have:
2.16 = h^2 x 6
Now we can solve for h.
Divide both sides by 6:
h^2 = 2.16/6
Take the square root of both sides:
h = √2.16/6
The answer is A.
