Answer 2

Answer:

₹7,500

Step-by-step explanation:

The perimeter of the floor = 250 m = 2(length of the floor+width of the floor).

2(l+b)=250                                      ...(i)

Area of the 4 walls = 2(l+b)*height given

=250*6

=1500 m³

Cost of painting its four walls = 5*1500

= ₹ 7,500
