Answer:

538,3m^2

Step-by-step explanation:

first of all, I find it really disturbing to use 3,14 as pi but I'll try my best.

1) Determine the area of the rectangle;

h.b= area of a rectangle

so here

15m.30m = 450 m^2

the area of the circle = pi.r^2

so here

7,5m^2.3,14 = 176,625m^2

but we only need the half of it so 176,625m^2/2 = 88,3125m^2 ~ 88,3m^2

then we must sum them all up;

88,3m^2 + 450m^2 = 538,3m^2
