Question

describe how you would determine the area of this composite figure (the shaded region). a) subtract the area of the circle from the area of the triangle. b) multiply the base of the triangle by the area of the circle. c) add the areas of the triangle and the circle. d) subtract the area of the triangle from the area of the circle.

Explanation:

Step1: Identify component shapes

The composite figure is made of a triangle and a circle.

Step2: Recall area - finding principle

To find the area of the shaded region (composite figure), we need to subtract the non - shaded part (circle) from the whole (triangle).

Answer:

A. Subtract the area of the circle from the area of the triangle.
