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