Answer:

79.625

Step-by-step explanation:

The area of a semicircle is half of the area of the circle. As the area of a circle is πr2. So, the area of a semicircle is 1/2(πr2 ), where r is the radius. The value of π is 3.14 or 22/7. The area of a rectangle is Length x Width. 5 is the diameter of the circle, and the radius is half of that

5 x 12 = 60

A = nr^2 =

A =3.14 x R^2 =

R = 5/2 = 2.5

R = 2.5

A = 3.14 x 2.5[tex]^{2}[/tex]

A = 3.14 x 6.25

A = 19.625

60 + 19.625

79.625
