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
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
B
20 x 15 is 450 and add it to the semi circle which us 88.4
Hope this helps u :D

11*4=44
6*2=12
44+12=56
y = 3(x+7/6)² - 25/12
