Answer:

c) The area of the adjoining figure is 77 sq. cm.

Step-by-step explanation:

Given figure is the semicircle

Dimeter = 14 cm

radius (r) = 14/2 = 7 cm

If area of circle = \pi r^2

Then area of the semicircle = \frac{1}{2} \pi r^2

= \frac{1}{2} \times \frac{22}{7}  \times  (7)^2\\= \frac{1}{2} \times \frac{22}{7}  \times  49\\= \frac{1}{2} \times22  \times  7\\= 11  \times  7\\= 77 cm^2

So, the area of the given semicircle is 77 sq. cm.
