Answer:

The answer to your question is letter C

Step-by-step explanation:

Data

height = h = 8 ft

width = w = 3 ft

diagonal = d = ?

Formula

We can use the Pythagorean theorem to solve this problem.

                    d² = h² + w²

Substitution

                    d² = 8² + 3²

Simplifying

                    d² = 64 + 9

                    d² = 73

Result

                    d = 8.5 ft
