Answer:
100 for the square
217.81 for the entire firgue
Step-by-step explanation:
For the square it's bh so do that formula
A = 10x10
A = 100
then for the semicircles that's half of a circle do the area of a circle formula and then multiply by half
A = 3.14×25
A = 78.54×0.5
A = 39.27
since we have 3 of them we are going multiply that by 3.
39.27 × 3 = 117.81
then we add them all up
117.81 + 100 = 217.81
