Question

the area of four walls of a room is 120 metre square if the length of the room is 2 is its breadth and the height is 4 find the area of the flour​

Answer 1

Answer:

The answer is 50$m^2$.

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 = 120$m^2$

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

=50$m^2$

∴ The answer is 50$m^2$.
