Find the area of the figure above
[π = 22/7]
[π = 22/7]
-
A.
12.5 cm2 -
B.
75.0 cm2 -
C.
78.5 cm2 -
D.
84.8 cm2
Correct Answer: Option D
Explanation
Area of the figure = Area of rect + area of semi circle
(=L times h + frac{1}{2}pi r^2\
5 times 15 + frac{1}{2} times frac{22}{7} times left(frac{5}{2}right)^2\
=75+frac{(22times 25)}{2times7}\
=75 + 9frac{23}{28}\
=84.8cm)
