Answer 2

Answer:

Convert all the given measures into same units. From the question,

Verandah has length of = 40 m = (40 × 10) dm = 400 dm [Because 1m = 10dm] Verandah has length of = 15 m = (15 × 10) dm = 150 dm

∴Area of the verandah = (l × b) = (400 × 150) dm2 = 60000 dm2

Now, Length of a stone = 6dm (given) Breadth of a stone = 5dm ∴Area of a stone = (l × b) = (6 ×5) = 30 dm2

∴Total number of stones required to pave the verandah = (Area of verandah/ Area of each stone) = (60000/ 30) = 2000
