Question

find the area of the figure if the upper portion is a semi circle​

Answer 1

Here’s your answer:
Length of rectangle = diameter of semicircle = 14cm

Breadth of rectangle = 10cm

Radius of semicircle = 14/2 = 7 cm

Area of rectangle = lb
= 14 x 10
= 140cm2

Area of semicircle = 1/2 πr2
= 1/2 x 22/7 x 7 x 7
= 1 x 11 x 7
= 11 x 7
= 77cm2

Now, area of figure = area of rectangle + area of semicircle
= 140 + 77
= 217 cm2
