Answer 1

To paint the walls of the room we should first see that shape of the walls i.e. if it is a square or a rectangle or all are squares or rectangles.

Based on that find the area of each wall depending on the shapes. If all are same find the area of ones side and the same area to it three more times. If they are different shapes find areas of all the side and add all of them.
