Question

the area four walls of a room is 120m2 If the length of the room is twice its breadth and the height is 4m, find the area of the floor.​

Answer 1

Step-by-step explanation:

if breadth is x

then, length is 2x

height=4m

area of four walls of a room=120m2

2*(length+breadth)*height=120m2

2*(x+2x)*4=120

2*(3x)*4=120

24x=120

x=120/24

x=5m

therefore, length=2*5=10m

breadth=5m
