Question

Can anyone help me WITH this question​

Answer 1

Step-by-step explanation:

length of verandah = 40 m

breadth of verandah = 15 m

area of verandah = length × breadth

= 40 m × 15 m

= 600 m²

length of each stone = 6 dm = 0.6 m

breadth of each stone = 5 dm = 0.5 m

area of each stone = length × breadth

= 0.6 m × 0.5 m

= 0.3 m²

$number \: of \: stones \: = \frac{600 \: {m}^{2} }{0.3 \: {m}^{2} } = 2000$
