the cost of 6 tiles at rate of 12.50 of per tile= 12.50×6=75

Answer 2

The cost at the rate of rs 12.50 per tiles is Rs.700

Step-by-step explanation:

1 m = 100 cm

Length of wall = 5 m = 500 cm

Width of wall = 3 m = 300 cm

Area of wall = $Length \times Breadth = 500 \times 300 = 150000 cm^2$

Length of tile = 25 cm

Width of tile = 10 cm

Area of tile = $Length \times Breadth = 25 \times 10 = 250 cm^2$

No. of tiles required =$\frac{150000}{250}=600$

Cost of 1 tile = Rs.12.5

Cost of 600 tiles =$12.5 \times 600 =7500$

Hence  the cost at the rate of rs 12.50 per tiles is Rs.700
