Question

A hall 125 metres long and 65 metres broad is surrounded by a verandah of uniform width of 3 metres. The cost of flooring the verandah, at Rs.10 per square metre is

• A. 11760 Rs
• B. 11780 Rs
• C. 19000 Rs
• D. 11800 Rs

Answer 1

Answer:

A. 11760 Rs

Area of the verandah = (125 + 2 × 3) (65 + 2 × 3) –125 × 65

= 131 × 71 – 125 × 65

= 9301 – 8125

= 1176 sq.metre

Cost of flooring = 1176 × 10 = 11760 Rs.
