2.5 is the answer( not sure)

Answer 2

Answer:

Step-by-step explanation:

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
