Answer 1

Answer:

₹ 17,672.5

Step-by-step explanation:

Given: Length = 22 m

Breadth = 16.5 m

The area of the hall = L × B = 22 × 16.5 = 363 m²

Margin of carpet = 75 cm = 0.75 m

Area of carpet = (22 - 2 × 0.75) (16.5 - 2 × 0.75)

⇒ (22 - 1.5) (16.5 - 1.5)

Area of the carpet = 20.5 × 15 = 307.5 m²

Portion uncovered = 363 - 307.5 = 55.5 m²

A meter length of the carpet = 1 m × 0.82 m = 0.82 m²

307.5/0.82 = 353.45 m of carpet

Cost of fencing the strip = ₹ 50 per meter

Cost of fencing the strip = 353.45 × 50

= ₹ 17,672.5

i.e. 17,672 rupees 50 paise
