Explanation:

The Radius of the larger semi circle =
(12)/(2) =
6
cm

Area of the 2 larger semi Circles =
(\pi r^(2) )/(2)
X2

=
(3.14X(6)^(2) )/(2) X 2

=
(113.04)/(2) X2

=
113.04
cm^(2)

Radius of the smaller semi circle =
(5)/(2) = 2.5cm

Area of the smaller semi circle =
(\pi r^(2) )/(2)
X2

=
(3,14X(2.5)^(2) )/(2) X 2

=
196.25
cm^(2)

Combined Area =
113.04 + 196.25

=
309 . 29cm^(2)
