Question

Find the number of square tiles each of sides 14cm which can be fitted on afloor of dimension 210cm by 140cm

Answer 1

Area of the floor = length × breadth

Length = 210cm

Breadth = 140cm

Area of the floor = 210 × 140

Area of the floor = 29400 cm^2

Now,

Area of square tile = (side)^2

side = 14cm

Area of square tile = (14)^2

Area of square tile = 196 cm^2

Number of tiles = (Area of floor) / (Area of square tile)

Number of tiles = 29400/196 = 150

therefore, we need 150 tiles to cover the floor.
