Answer 2

Answer:

The area of shaded portion is 63 sq. cm

Step-by-step explanation:

Area of rectangle = length x breadth

= 14 x 10

= 140 sq. cm

radius of circle = 1/2 (14) = 7 cm

Area of semicircle

 $=\frac{1}{2} \times \pi r^2 \\=\frac{1}{2}\times \frac{22}{7} \times 7 \times 7\\= \frac{1}{2} \times 22 \times 7\\= \frac{1}{2} \times 154 sq. cm.\\ = 77 sq. cm$

Area of shaded portion = Area of rectangle - area of a semicircle

= 140 - 77

= 63 sq. cm
