Answer:

Length = 10.81 m

Width = 5.69 m

Step-by-step explanation:

Let the width of the room be [tex]x[/tex].

As per question, length is 1.9 times its width.

Therefore, length is, [tex]l=1.9x[/tex]

Perimeter is 33 meters.

Perimeter is given as,

[tex]P=2(l+x)\\33=2(1.9x+x)\\33=2(2.9x)\\33=5.8x\\x=\frac{33}{5.8}=5.69\textrm{ m}[/tex]

Therefore, width of the room is 5.69 m.

Length of the room is, [tex]l=1.9x=1.9\times 5.69=10.81\textrm{ m}[/tex]

Therefore, the length of the room is 10.81 m.
