Q8: What is the area of the shaded portion?

Quant Practice Questions for ACT - 3 | Mathematics for ACT

Quant Practice Questions for ACT - 3 | Mathematics for ACT  View Answer

Ans: The area of the shaded portion equals the area of the rectangle minus the area of the triangle. Area of rectangle = length × width = 7 inches × 3 inches = 21 square inches. Area of triangle = 1/2 × base × height =1/2 × 2 inches × 3 inches = 3square inches. Area of shaded region = 21square inches – 3 square inches = 18 squareinches. To solve this problem: (1) Find the areaof the outside, larger figure; (2) Find the area ofthe smaller, undefined figure; (3) Subtract thearea of the unshaded figure from the area of theoutside larger figure.
