Question

A wall 4.8m long and 3.5m is covered with rectagular tiles of size 12 cm by 10 cm find the total cost of tiles at the rate of rupees 2.50 per tile

Answer 1

Step-by-step explanation:

Length of wall = 4.8 m

Breadth of wall = 3.5 m

Area of wall = 4.8 × 3.5

= 16.8 m²

Length of tile = 12 cm = 0.12 m

Breadth of tile = 10 cm = 0.01 m

Area of tile = 0.12 × 0.01

= 0.0012 m²

No. of tile on the wall = 16.8/0.0012

= 168000/12 = 14000 tiles

Cost of one tile = Rs. 2.50

Cost of 14000 tiles = 14000 × 2.50

= Rs. 35000
