Answer:

5 m wide and 7 m long

Step-by-step explanation:

Let the width of the room = [tex]x[/tex]

Therefore, length of the room = [tex]x[/tex] + 2 (as it's 2 m longer than the width)

So total perimeter = 2 x width + 2 x length:

 [tex]2x+2(x+2)=24[/tex]

Now rearrange and solve for [tex]x[/tex]:

[tex]2x+2x+4=24\\4x=20\\x=5[/tex]

So width = [tex]x=5[/tex]

and length = [tex]x+2=5+2=7[/tex]

Therefore, the dimension of the room is 5 m wide and 7 m long.
