Find the area of the shaded portion in figure 2.
Solution:
The area of the shaded portion can be found out by subtracting the area of the unshaded rectangle from the area of the triangle.
Area of the triangle(A) = 1/2 × Base × height
A = 1/2 × 40 × 16
A = 20 × 16
A = 320m²
Area of the unshaded triangle = 8 × 10 = 80 m²
Area of the shaded area = 320 - 80 = 240m²

The area of the shaded portion can be found out by subtracting the area of the unshaded rectangle from the area of the triangle.
Area of the triangle(A) = 1/2 × Base × height
A = 1/2 × 36 × 15
A = 18 × 15
A = 270 m²
Area of the unshaded triangle = 6 × 12 = 72 m²
Area of the shaded area = 270 - 72 = 198m²
