Question

A room 10 m long and 8 m wide is carpeted leaving 50 cm space from the sides. Find the
cost of the carpet at the rate of 90 per sq. m.​

Answer 1

Answer:

Given ;

Length = 10 m = 1000 cm

Breadth = 8 m = 800 cm

• Length to Carpet = (1000 - 2(50)) = (1000 - 100) = 900 cm = 9 m
• Breadth to Carpet = (800 - 2(50)) = (800 - 100) = 700 cm = 7 m

• Cost Of Carpeting :

↠ Cost = Area × Rate

↠ Cost = (9m × 7m) × Rs. 90 per m²

↠ Cost = 63 m² × Rs. 90 m²

↠ Cost = Rs. 5670

∴ Cost of Carpeting of Floor is Rs. 5670
