Question

A tile measure 10*10cm how many such tiles are required to cover a wall of 4m*2.5m

Answer 1

dimension of tile = 10*10 sq cm
area of tile = 100 sq cm
converting the area in m = 100/(100*100)
= 0.01 sq m
dimension of wall = 4m * 2.5m
area of wall = 10 sq m
no. of tiles = (area of wall) / (area of tile)
= 10/0.01
= 1000
no. of tiles required = 1000

Answer 2

no. of tiles required=1000.
