Question

Question 9 (iii)

The adjoining figure represents a rectangular lawn with a circular flower bed in the middle. Find:

The area of a lawn excluding the area of the flower bed.

Answer 1

Length of rectangular lawn = 10 m
Breadth of the rectangular lawn = 5 m
And radius of the circular flower bed = 2 m
$\therefore$ Area of lawn excluding the area of the flower bed
= Area of lawn - area of the flower bed
= 10 x 5 - $\pi \times 2^2$
$=50-12.56$
$=37.44m^2$
