Answer: 98 feet

Explanation:

First, you need to find the hypotenuse, which is always opposite from the right angle.

Because this isosceles triangle consists of 2 right triangles, they are congruent which means that you can simply just divide 48 by 2 to find the base of one of the triangles, 24.

Next, use a^2 + b^2 = c^2

7^2 + 24^2 = c^2

49 + 576 = c^2

625 = c^2

25 = c

Now, you can find the perimeter.

48 + 25 + 25 = 98 feet

Hope this helped :)
