L = lenght
W = width
so
{L,W} = {6,10} or {10,6}
but L > W so
L = 10
W = 6
W = width
so
{L,W} = {6,10} or {10,6}
but L > W so
L = 10
W = 6

Perimeter of the floor of a room = 18 metre
Height of the room = 3 metre
To find:
The area of 4 walls of the room.

We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.
The curved surface area of the cuboid is
Where, h is height, l is length and b is breadth.
Perimeter of the rectangular base is 2(l+b). So,
Putting the given values, we get
Therefore, the area of 4 walls of the room is 54 sq. metres.
