If it is asking if that equation is the quadratic formula, then the answer is false. The reason why is that the first 'b' should be negative
The quadratic formula is

The height of the tower roughly equals 41.421 meters.
Surface area of a rectangular pyramid = A + 1/2 p s
Where:
A = area of the base
p = perimeter of the base
s= salnt height = 5 in
A = Area of a rectangle = length x width = 8 x 4 = 32 in2
Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2
SA = 32 + 1/2 * 24 * 5 = 92 in2
