Answer:
19.9cm^2
Step-by-step explanation:
Rectangle: l*b
= 3*4 = 12cm^2
Diameter 4 Semicircle:
Area of semicircle = 1/2*pi*r*r
= 1/2 * 3.14 * 2 * 2
= 3.14 * 2
= 6.28cm^2
Diameter 2 semicircle:
= 1/2 * 3.14 * 1 * 1
= 3.14/2
= 1.57cm^2
Adding all areas=
12 + 6.28 + 1.57
=19.85
to 1 decimal place = 19.9cm^2
