Answers
Answer:
Length of auditorium = 20m
Breadth of auditorium = 15m
Height of auditorium = 10m
Rate of painting walls =
Cost of painting the four walls
We need to paint the four walls of the auditorium.Hence, we need to find the lateral surface area of the auditorium.
Lateral Surface Area of Auditorium
= 2h(l+b)
= 2(10)(20 + 15)
= 20(35)
=
Cost of painting four walls
= Rate × Area
= 750 × 700
= Rs.525000
Therefore, the cost of painting four walls of the auditorium is Rs.525000 only.
