Question

Gordon is building a rectangular pavement 4 metres long and 2 metres wide. He is using square slabs with 50 centimetre edges. How many slabs does he need?

Answer 1

Answer:

The number of slabs required is 32.

Step-by-step explanation:

Length of Pavement = 4m

Breadth of Pavement = 2m

Area of Pavement = l x b = 4 x 2 = 8m²

Length of square slabs (in meters) = 50/100 = 0.5m

Area of square slabs = a² = 0.5² = 0.5 x 0.5 = 0.25m²

Number of slabs required to cover the pavement =

Area of slabs / Area of Pavement = 0.25 / 8 = 32

Hence the number of slabs required is 32.
