Question

area of shaded region
​

Answer 1

Answer:

392 sq.cm.

Step-by-step explanation:

Shaded area = Area of half-circle  - Area of a trapezoid

Half-circle Area = 1/2 * pi * 28 * 28

= 11 * 4 * 28 = 1232 sq.cm.

Trapezoid Area = 1/2 * ( 56 + 28 ) * 20

= 840 sq.cm.

## Shaded area = 1232-840 = 392 sq.cm.
