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/-
