Question

A carpet is 6m 20 cm long and 3m 40 cm broad is bounded by a tape around the edges.
i) Find the length of the tape needed.
ii) Find the cost of the required tape if the cost of the tape is Rs. 4 per metre
a) 9.6 cm, Rs. 76.80
b) 19.2 m, Rs. 76.80
c) 19.2 m, Rs. 23.2
d) 9.06 m, Rs. 76.80

Answer 1

Answer:

The cost of the tape required to bound the carpet around its edges is Rs. 57.5.

• A carpet is 6m 20 cm long and 3m 40 cm broad.
• Length and breadth of the carpet is 6.2m and 3.4 m.
• We have to bound the carpet with a tape around the edges of the carpet.
• Therefore, to find the length of the tape required to bound the carpet, we need to find the perimeter of the carpet.
• Perimeter of the carpet = 2( length + breadth)

= 2×6.2 + 2×3.4 = 12.4+6.8 = 19.2m

• The length of the tape required will be equal to 19.2m
• Cost of the tape is 3 per metre.
• Now the cost of tape required will be = 3 × 19.2 = Rs. 57.5
