Answer:

The area of the shaded region is 66.4cm²

Explanation:

First you need to find the area of the whole triangle. The formula used for this is
(1)/(2) * base * height.

A= .5 * 18 * 9.2 A= 82.8 (Area of full triangle)

Next, you need to find the area of the small, unshaded triangle.

A= .5 * 8 * 4.1 A= 16.4 (Area of unshaded section)

Subtract the smaller area to find the area of the shaded region.

A= 82.8 - 16.4 A= 66.4 (Area of shaded region)
