Question

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

Answer 1

Answer:-

$number \: of \: stones \: required \: = \frac{area \: of \: verandha}{area \: of \: stone}$

$number \: of \: stones \: = \frac{40 m \times 15m}{6dm \times 5dm}$

$1 \: m \: = 10 \: dm$

$= \frac{40 \times 10 \times 15 \times 10}{6 \times 5}$

$= 2000 \: stones$
