Answer 2

Answer:

₹90

Step-by-step explanation:

We have that,

Perimeter of the rectangular hall = 250 meters

Height = 6 cm = 0.06 meter

Since, we know,

Lateral surface area of a rectangular prism = Perimeter × Height

i.e. Lateral surface area of a rectangular hall = 250 × 0.06

i.e. Lateral surface area of a rectangular hall = 15 m²

Since, the cost of painting the wall = ₹6 per square metre

Thus, the cost of painting 15 m² = 6 × 15 = ₹90

Hence, the cost of painting the four walls is ₹90.
