The area of a right triangle with one leg measuring 5 ft. and hypotenuse measuring 13 ft. is

First, solve for the other leg. After using the Pythagorean Theorem, we found out that the other leg is 12ft.

Therefore, 

Area = (Base x Height)/2 
A = (5ft.x 12ft.)/2 = 30 ft. ^2

The area of the triangle is 30 square feet.
