Question
The length, breadth and height of a room are in the
ratio 2:3:4. If the breadth and height are halved while the length is doubled, then the total area of the four walls of the room willSolution
Let length = 2, breadth = 3 & Height of room = 4 So original total area of four walls = 2(2 x 4 + 3 x 4) = 2(8 + 12) = 2 x 20 = 40 Then new length = 4, new breadth = 1.5 and new height = 2 So new total area of four walls = 2(4 x 2 + 1.5 x 2) = 2(8 + 3) = 2 x 11 = 22 ; Hence decrease in total area of four walls = (40 - 22)/40 x 100 = 45%
