Answer:
The diagonal is 14.4 feet.
Step-by-step explanation:
The Pythagorean Theorem: a^2 + b^2 = c^2
Substitute 8 and 12 with a and b because they are the legs.
That gets you the equation 8^2 + 12^2 = c^2
Which then gets you, 64+144 = c^2
208 = c^2
Then, square root each side to get rid of the 2 exponent on the c.
which in the end gets you 14.42, which rounds to 14.4
