Chapter 12.8, Problem 39CCR

To determine

To find : Area of given figure.

Answer to Problem 39CCR

  $1240.63{\text{ m}}^{\text{2}}$

Explanation of Solution

Given information :

The given information is,

Diameter of semi-circle = $25$ m

And breadth of rectangle = $25$ m

Length of rectangle = $30$ m

Formula Used:

Area of rectangle = length × breadth

Area of semi-circle = $\frac{\pi r^2}{2}$

Calculation :

  

Area of given figure = $2\times \frac{\pi r^2}{2}+l\times b$

  $\begin{array}{l}=(3.14){\left(\frac{25}{2}\right)}^2+25\times 30\\ =490.63+750\\ =1240.63{\text{ m}}^{\text{2}}\end{array}$
