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

Step-by-step 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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
