Answer 1

Question :-

1. A verandah is 40 m long and 15 m broad. It is to be paved with stones, each measuring 6dm by 5 dm. Find the number of stones required.

Answer :-

Lenght of verandah = 40 m

Breadth of verandah = 15 m

Area of verandah = Lenght × Breadth

=> 40 × 15

=>

$600 {m}^{2}$

Area of each Stone = Lenght × Breadth

=> 6dm×5dm

=> $30d {m}^{2}$

Number of stone =

$\frac{area \: of \: verandah}{area \: of \:each \: stone}$

=> $area \: of \: stone = \cancel \frac{600}{30 \times {10}^{ - 2} }$

=> Number of stone = 2000
