Question

Find the area of the parallelogram below by decomposing into two triangles. The figure is not drawn to scale.

Answer 1

Explanation:

area of a triangle = (½)(base)(height)

You can divide the parallelogram into two congruent triangles with base = 8 mi and height = 10 mi.

area of each triangle = (½)(8)(10) = 40 mi²

area of parallelogram = 2(40) = 80 mi²
