Answer:
area: 144 in; perimeter: 50 in
Step-by-step explanation:
The height of this area is the length of the dotted line. Call it h. Then, according to the Pythagorean Theorem, 5^2 + h^2 = 13^2, so that h^2 = 144 and h = 12 (in).
The area of this parallelogram is then A = (width)(height) = (12 in)(12 in) = 144 in^2.
The perimeter is P = 2(12 in) + 2(13 in) = 50 in
