Ahmad wants to make a path using small stones arount a flower bed. (Look at the picture below)Ahmad needs 50 kg of stones for each square metre of path. Stone are sold in bags weighting 0.75 tonnes.Calculate how many bags of stones he needs to buy.Show how you worked out answer

Area of path = (8 + 1 + 1)(6 + 1 + 1) – (8 x 6) m2

= (10 x 8) – (8 x 6) = 80 – 48 = 32Stones he needs = 32 x 50 kg = 1600 kg = 1.6 tonnesThe number of stones he needs to buy = 1.6 : 0.75 = 2.13333 So, he need to buy 3 bags of stones
