Question

How Many Square Carpet Tiles, Each measuring 0.5m By 0.5m, will be needed to cover a floor 111 m2 ???

Please show your working and explain what you are calculating.

Answer 1

0.5m By 0.5m = 0.25m²

area of a tile = 0.25m²

floor area = 111m²

pcs of tiles(N) = floor area / area of a tile

N = 111m² / 0.25m²

N = 444 pcs. → answer

--regards--

Answer 2

area of each tile is  0.5 * 0. 5 = 0.25 m2 because area of a square if side square...

total given area = 111 m2

no of tiles = total area / each tile =   111 / 0.25 = 444 tiles..

i hope i helped..
