Question

how many rectangular tiles 10cm by 7 cm will be required to cover a floor 14 M long and 12.5 M broad and what will be the cost at 70 rupees per 100 tiles​

Answer 1

Answer:

Step-by-step explanation:

Length of tile = 10cm

Width of tile = 7cm

Area of tile = 70sq cm

Length of floor = 14 m = 1400cm

Width of floor = 12.5cm = 1250cm

Area of floor = 1400*1250 sq cm

No. Of tiles required= (1400*1250) ÷ 70

=25, 000

Given, cost of 100 tiles = 70/-

Cost of 25,000 tiles = (25,000*70) ÷ 100

17,500/-
