Question

a bathroom has square floor with side 3m.Find the cost of covering it with tiles at the rate of Rs.200 per square meter.

Answer 1

Find the area of the floor:

Area of a square = Length x Length

Area of the bathroom floor = 3 x 3 = 9m²

-

Find the Cost:

1 m² = Rs 200

9m² = 200 x 9 = Rs 1800

-

Answer: The cost will be Rs 1800

Answer 2

Given : Side = 3 m , Cost of covering per m² = Rs.200

So,area of floor = (Side×Side)square units = 3×3 m² = 9 m²

Cost of covering per meter square = Rs.200

So,cost of covering floor of area 9 m² = RS (Cost of 1 unit × area )

200 × 9 = Rs 1800

Ans : Cost of covering floor of side 3m = Rs 1800
