A marble tile measures 12cm by 10 cm . How many tiles will be required to cover a wall of

size 4m by 3m? Also, find the total cost of the tiles at Rupees 22.50 per tile.​

Answer 1

Answer:

Rs 22500

Step-by-step explanation:

4 m = 400 cm

3 m = 300 cm

So, area of the wall = (400×300) cm^2

= 120000 cm^2

Dimensions of the marble tiles = 12cm×10cm

So, area of each marble tile = (12×10) cm^2

= 120 cm^2

So, number of marble tiles needed = (120000÷120) tiles

= 1000 tiles

So, total cost = Rs (1000×22.5)

= Rs 22500

Answer 2

Answer:1000 tiles

22500 rupees

Step-by-step explanation:

first let's find area of tile = (l×b)=120cm square

let convert size of wall from m to cm be 400cm and 300 cm

now find area of wall 300×400=120000cm square

by dividing area of wall by area of tile we get no of tiles = 12

0000/120= 1000 tiles

total cost of tiles=22.50 ×1000 = 22500 rupees
