Given

• The floor of a rectangular hall has a perimeter of 250 m. Its height is 6 m.

To find

• The cost of painting its four walls (including doors, etc.) at the rate of 6 Rs per square metre.

Step-by-Step-Explaination

Height of rectangular =6m

Perimeter =250m

We know that Perimeter of rectangle=2(l+b) 250=2(l+b)

Area of four walls =2(l+b)h

We know the value of 2(l+b)

Area of four wall=250×6

Area of four wall =1500m^2

Cost of painting =rate × area Cost of painting four walls =250 × 1500

Cost = ₹ 3750000
