In parallelogram ABCD, AB=125cm, AD=132cm, and the length of diagonal AC is 37cm. The area of the parallelogram, in cm2, is
It's very simple.
Two identical triangles with side lengths of 125 cm, 132 cm, and 37 cm form a parallelogram ABCD.
Heron's formula gives the area of a triangle when the length of all three sides is known.
A = sqrt[s(s - a)(s - b)(s - c)] ( s => semiperimeter ) s = 1/2(a + b + c)
