Question

12. A marble tile measures 10 cm × 12 cm. How many tiles will be required to cover a wall of size 3 m × 4 m? Also, find the total cost of the tiles at the rate of Rs 2 per tile

Answer 1

=]Area of the wall is (3×4)m²

= 12m²

now,

=>area of a marble is (0.1×1.2) m²

= 0.12

=>No. of marble tile = (12÷0.12)

=100

=>rate of each tiles is Rs. 2

=>then cost of 100 tiles is Rs. (2×100)

=Rs. 200
