Answer:
Step 1. Given data :
Given,
length of the floor = 18 m ,
width of the floor = 12 m and
cost of flooring per tile = Rs. 80
Step 2. Finding the areas :
Then, area of the floor
= length × width
= 18 × 12 m²
= 216 m²
and the area of each square tile
= 12 × 12 cm²
= 144 cm²
(144 / 10000) m²
Step 3. Finding number of square tiles :
∴ required number of square tiles to pave the floor
= area of the floor / area of each tile
= 216 / (144 / 10000)
= (216 × 10000) / 144
= 15000
Step 4. Finding the cost of flooring :
∴ the cost of flooring at the rate of Rs. 80 per tile
= Rs. (15000 × 80)
= Rs. 1200000
