The area of four walls of a room is 120 m^(2) . If the length of the room is twice its breadth and the height is 4 m, find the area of the floor.

The area of four walls of a room is 150 m^(2) .If the length of the room is twice its breadth and the height is 5 m ,find the area of the floor.

The area of four walls of a room is 120 m . The length of the room is twice its breadth. If the height of the room is 4 m, what is area of the floor ?

The area of the four walls of a room is 2640 sq. m and the length is twice the breadth and the height is given as 11 m. What is the area of the ceiling?

The area of the four walls of a room is 660 m^(2) and its length is twice its breadth. If the height of the room is 11 m, then area of its floor (in m^(2) ) is

The area of the four walls of a room is 120m2 and the length is twice the breadth. If the height of the room is 4m, then the area of the floor is (a) 48m2 (b) 49m2 (c) 50m2 (d) 52m2

The cost of flooring at Rs.20 per m^(2) is Rs.4,200. If the length of the room is 21m, then its breadth is:

The area of the 4 walls of a room is 77 m^(2) . The length and breadth of the room are 7.5 m and 3.5 m respectively. Find the height of the room.
