Answer 1

218.55

Explanation:

total area = semi circle + parallelogram

= (1/2 π 6²) + (9 x 18)

= 56.55 + 162

= 218.55 sq. units

Answer 2

388

Explanation:

We need to find the area of the semicircle and parallelogram separately and then combine.

The formula for the area of a semicircle is 1/2(pi*r^2)

r = 12. 12^2 = 144

1/2(pi*144) = 226..1946711 which we can just round to 226

The formula for the area of a parallelogram is bh

b = 18, h = 9. 18*9 = 162.

226+162 = 388
