Find the perimeter and area of a right triangle if one leg measures 24 ft. and the other leg measures 70 ft. Please show the steps so I can do the next one. Thanks

First, use the Pythagorean Theorem to find the hypotenuse.

a^2 + b^2 = c^2
24^2 + 70^2 = c^2
576 + 4900 = 5476
c = 74

Now you have the three sides for the perimeter.

A = 1/2bh
A = 1/2 * 24 * 70
A = (1/2) * 1680
A = 840 sq. ft.
