Suppose he uses 1 slab for width (55 cm) and 1100 cm long = (1100/55) = 20 slabs
But he uses 2 slabs or width
Number of slabs = 20x 2 = 40
But he uses 2 slabs or width
Number of slabs = 20x 2 = 40

100 cm = 1 m
2 slabs wide = 2(55) = 110 cm = 1.1m
11 m /1.1 m = 10 slabs long
2 × 10 = 20
2 slabs wide = 2(55) = 110 cm = 1.1m
11 m /1.1 m = 10 slabs long
2 × 10 = 20
