Question 754926
Pythagorean problem.
A right angled triangle with one side
= 100ft and the other = 50ft.
The slope from the ends of the sides
is the hypotenuse. This is the diagonal.

100^2 + 50^2 = diagonal^2
10000 + 2500 = diagonal^2
12500        = diagonal^2
    diagonal = square root of 12500
    diagonal = 111.8 = 112 ft.
Hope this helps
:-)
