Answer:
A. 62 units
Explanation:
To find the perimeter of the rectangle, you have to use the Pythagorean theorem.
a^2 + b^2 = c^2 - Formula
24^2 + b^2 = 25^2 - Plug in values
576 + b^2 = 625 - Simplify
b^2 = 49 - Isolate the variable
b = 7 - Solve
After finding the height, find the perimeter.
P = 2b + 2h
P = 2(24) + 2(7)
P = 48 + 14
P = 62 units
