Solution
The length and breadth of the room are in the ratio 7:4.
So, suppose length and breadth of the room are 7x and 4x respectively.
Height of room = 3.4 m
We know that area of four walls of room = 2h(l + b)
And given area of four walls of room = 224.4
So, the area of four walls of room is given by;
So, length of room = = 21 m
And breadth of room = = 12 m
