Question

A hall 20 m long and 18 metre board.find the cost of carpeting it at rupees 10 per m.square after leaving a margin of 1 m all around​

Answer 1

Answer:

Rs 2880

Step-by-step explanation:

Length of the hall = 20m

Breadth of the hall = 18m

Area of the hall = 20×18 = 360 sq m

Length of the carpet = 20-1×2 = 20-2 = 18 m

Breadth of the carpet = 18 - 2×1 = 18-2 = 16m

Area = L × B = 18× 16 = 288 sq m

Cost of carpetting 1 sq m = 10

Cost of carpetting 288 sq m = 288×10 = Rs 2880
