Answer 2

400 paving stones each measuring 10 dm by 9 dm are required.

Step-by-step explanation:

Length of the stone = 10 dm

Width of the stone = 9 dm

Area of the stone = 10 x 9 dm² = 90 dm²

Length of ham = 60 m = 60 x 10 dm = 600 dm   [As 1 m = 10 dm]

Width of ham = 6 m = 6 x 10 dm = 60 dm

Area of ham = 600 x 60 dm² = 36000 dm²

Number of stones required = $\frac{36000}{90}$ = 400

Hence, 400 paving stones each measuring 10 dm by 9 dm are required.
