Question

a marble measures 20cm by 15 cm. How many tiles will be required to cover a wall of 5m by 3m?get brainliest marked​

Answer 1

Answer:

[1m = 100cm]

area of wall = l×b

L= 5m = 500cm. B= 3m = 300cm

500cm×300cm = 150000cm²

area of marble(tile) = l×b

L= 20cm. B= 15cm

20cm×15cm = 300

number of tiles = area of wall ÷ area of marble (tile)

= 150000÷300

=500

therefore 500 tiles are required
