Answer 1

A. The area of the shaded triangle = 11.25 units²

B. The area of the trapezoid = 40 cm²

C. The area of the parallelogram = 36 units².

How to Find the Area of Shapes?

The area of a triangle = 1/2 × base × height of triangle.

The area of a trapezoid = 1/2 × (sum of the trapezoid bases) × height of the trapezoid.

The area of a parallelogram = base × height of the parallelogram.

A. The area of the shaded triangle = 1/2 × base × height of triangle = 1/2 × 4.5 × 5 = 22.5/2

The area of the shaded triangle = 11.25 units²

B. Sum of the trapezoid bases = 12 + 8 = 20 cm

Height of the trapezoid = 4 cm

The area of the trapezoid = 1/2 × (20) × 4

The area of the trapezoid = 80/2

The area of the trapezoid = 40 cm²

C. Base of the parallelogram = 6 units

Height of the parallelogram = 6 units

The area of the parallelogram = 6 × 6

The area of the parallelogram = 36 units².
