Area of the semi circle = 215.65 sq inchesStep-by-step explanation:Here, given: The perimeter of the semi circle = 60.27 inches

Let us assume the radius of the circle = r

Now, the perimeter of the semicircle is given as :

P = πr + 2r⇒ πr + 2r = 60 . 27

or, r(π + 2) = 60. 27 ⇒ r (3.14 + 2) = 60.27

or, r x 5.14 = 60.27

or, r = 60.27/5.14 = 11.72 inches

⇒

The radius of the circle is 11.72 inches.Now, the

AREA of the semicircle =Substituting r = 11.72 in, we get:

A = 215.65 sq inches
