Width of the rectangular room = 4/7 x units.

Perimeter = y units.

y = 2(length + width)

y = 2(x +

4 over 7

y =

22 over 7

Now the 2nd part of the problem.

Find the length if its perimeter is 4400 cm.

Using the above equation, we will find the vlaue of 'x' by putting 'y'=4400. We get,

4400 =

22 over 7

1400 cm = x.

So the length measures 1400 cm.
