Answer 2

Answer:

500 tiles need to be used.

Step-by-step explanation:

Given : The side of a square tile is 10cm. One side of a wall which is 2.5m long and 2m high

To find : How many tiles can be fixed on one fixed on one side of a wall?

Solution :

The side of a square tile is 10 cm=0.1 m.

Area of one tile = 0.1*0.1= 0.01 meter square

One side of a wall which is 2.5 m long and 2 m high,

Area of wall = 2.5*2=5.0 meter square .

Number of tiles = Area of wall / Area of the tile

Number of tiles = 5.0/0.01

Number of tiles =500

Therefore,  500 tiles need to be used.
