Find the area of the figure above
[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)
