Question

a house 20m long and 15m wide is surrounded by a verandah of uniform width of 3m find the cost of flooring the verandah at rs 200 per square metre

Answer 1

Answer:

49200 rs.

Step-by-step explanation:

area of house = 20m×15m = 300

width of varandah = 3m

area of varandah =(300-(20-3)×(15-3))

=300-204

= 96

cost of flooring the varandah = 96 ×200

=Rs.19,200  

Answer 2

The length of the verandah= 20+3=23

The breadth of the verandah= 15+3=18

Area= L×b

=>23×18=414

Cost of flooring= 414×200=82800

Therefore cost of flooring= 82,800
