Answer:
37=c
Explanation:
We can find this by using the Pythagorean theorem
The width and the lengths are the legs of the triangle. The diagonal is the hypotenuse.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 +36^2 = c^2
400 +1296 = c^2
1336 = c^2
Take the square root of each side
sqrt(1336) = sqrt(c^2)
Since c has to be positive since it is a length
36.55133377 = c
Rounding to the nearest foot
37=c
