Question

The area of four walls of a room is 150. If the length of the room is twice it's breadth and the height is 4metre,find the area of the four wall

Answer 1

Here is the answer for your question


Let breadth be x m
So, length = 2x m

So, 2*4*(2x+x) = 120
or, 3x = 15
or, x = 5

So, area of floor = 5*(2*5)m2 = 50m2
