Question

In the given figure, find the area of the region excluding the three circles, rounded to the nearest $c{m}^2$?

• A. $41$
• B. $43$
• C. $45$
• D. $47$

Answer 1

The correct option is A $41$

Required area $=$ Area of rectangle $-3$$\times$area of $1$ circle

$=24\times 8-3\times \frac{22}{7}\times 4\times 4$

$=192-\frac{1056}{7}$

$=\frac{1344-1056}{7}=41{cm}^2$
