Answer 2

Answer:

106.75 cm^2

Step-by-step explanation:

First,

Diameter of semi circle = 7cm

R=D/2

R=7/2= 3.5cm

Radius = 3.5cm

Now,

Area of semi circle = 1/2 pi R^2

= 1/2×22/7×3.5×3.5

=11/7×12.25

=19.25cm^2

So,

Area of whole rectangle = l×b

=7×18

=126 cm^2

Therefore,Area of shaded portion

=126-19.25

=106.75 cm^2
