Question

A marble tile measures 10 cm× 8cm. How many tiles will be required to cover a wall of size 6m × 4m. Also find the total cost of the tiles at rupees 25 per tile

Answer 1

First we convert metre in cm
therefore
600×400=Area
240000m=Area

area of tile=6×4
=24

Required tile=240000÷24
=10000
total cost=10000×25
250000
2,50,000 is total cost
