A hall with dimensions 25 metres long and 15 metres broad is surrounded by a path of uniform width of 3.5 metres. The cost of flooring the path, at ₹25.50 per square metre is:
Answer & explanation
Correct answer: option 1
Length of the hall together with the path
= 25 + 2 × 3.5 = 32 m
The breadth of the hall together with the path
= 15 + 2 × 3.5 = 22 m
The area of the path
= (32 × 22 – 25 × 15) = 329 m2
The cost of flooring the path
= 329 × 25.50 = 8389.5
