Answer:
Step-by-step explanation:
the figure is divided into 2 semi circles and a square
so the area of the figure will be area of the 2 semi circles + area of the square
area of the 1st semicircle = 1/2 r^2
= 1/2 × 3.14 × 5^2
( radius = 5 since diameter is 10 and radius = d/2 )
= 1/2 × 3.14 × 25
= 12.5 × 3.14
= 39.25
area of the 1st semi circle = area of the 2nd semi circle = 39.25 m^3
area of the square = s × s
s = 10m
∴ area = 10 × 10 = 100 m^2
∴ area of the figure = 39.25 + 39.25 + 100
= 178.5 m^2
