A rectangular room is 18 m long and 12 m wide. A path 2 m wide is all around it. Find the cost of construction the path at the rate of rupees 100 per m^2.
Answers
Answer: Rs6400
Step-by-step explanation: Area rectangular room = l x b
= 18 x 12
= 216 m^2
Area of rectangular room with 2m wide path = (l+2) x (b +2)
= (18+2) x (12+2)
= 20 x 14
= 280m^2
Area of path = Area of rectangular room with 2m wide path - Area rectangular room
= 280-216
= 64m^2
The cost of construction the path = 100 x 64
= 6400 Rs
