Question

• A marble tile measures 25 cm by 20 cm. How many tiles will be required to cover
a wall of size 4 m by 3 m?​

Answer 1

Answer:

240 tiles

Step-by-step explanation:

measure of each tile = 25*20

area of each tile = 500 cm²

dimensions of wall = 4*3 = 400*300

area of wall = 120000 cm²

no. of tiles = 120000/500

                  = 240 tiles

Answer 2

HEY MATE HERE IS UR ANSWER.

AREA OF MARBLE TILE = 25 X 20 = 500cm²

AREA OF WALL= 4 X 3 = 12m²= 120000cm²

Now, THE NO. OF TILES = AREA OF WALL / AREA OF ONE TILE

= 120000/500

= 240 TILES ARE REQUIRED..
