Question

The shape of a park is a rectangle bounded by semi circle at the end each of radius 17.5m . Find the area and perimeter of the park

Answer 1

Answer:

. It is assumed that the shape of the

park is a square: Area of square-

= a2 = 35^2 =1225m2. (i)

Area of 4 semicircles=2πr 2

= 2x3.14x17.5^2 = 1923.25m2. (2)

(i) + (2) =1225 +1923.25 =3148.25

m2. Ans

perimeter=4xπr=4x3.14x17.5

=219.80m
