Problem

Two identical right-angled triangular wooden pieces each have hypotenuse 13 cm13\,\text{cm} and one leg 5 cm5\,\text{cm}. They are placed so that their hypotenuses coincide exactly and their right angles lie at opposite ends, forming a parallelogram. The area of the resulting parallelogram is (a) 156 cm2^2 (b) 65 cm2^2 (c) 60 cm2^2 (d) 120 cm2^2
