Answer 2

Answer:

50 meter square

Step-by-step explanation:

Let breadth of the room = b m

Length= 2b m

Height= h= 4m

1) area of the four walls of the room = 2(length+breadth)*h

2(2b+b)*4=120m^2

8*3b=120

b=120/(8*3)

b=5m

Therefore

Breadth=b=5m

Length=2b=2*5=10m

2)area of the floor= length*breadth

=10m*5m

=50m^2
