Answer:
30 square feet
Explanation:
To find the area of a right triangle you use the formula (leg x leg)/2. So to find the area, first you need to have both of the leg measurements, so you need to use Pythagorean's theorem. After using the theorem, you get 12 feet for the measurement of the other leg, so you multiply 12 by 5. 12 times 5 is 60, so you divide that by 2 (as seen in the original formula) and get your answer of 30.
