area of the shaded portion = 3758.86 m²
Step-by-step explanation:
Area of Largest Circle = π (35)²
Using π = 22/7
= (22/7) * 35²
= 3850 m²
Area of Circle with radius 3.5 m = π (3.5)² = 38.5 m²
Area of Circle with radius 2.8 m = π (2.8)² = 24.64 m²
Area or rectangle = 7 * 4 = 28 m
area of the shaded portion = 3850 - (38.5 + 24.64 + 28)
= 3850 -91.14
= 3758.86 m²
