Answer: 98 feet
Step-by-step 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 :)
