Answer 3

Since the perimeter of a rectangle is 2L + 2W you can just put together a quick formula with what you were given:

90cm = 2(W + 9) + 2W

Now just solve for W:
\[90 = 2(W+9)+2W\]\[90 = 2W + 18 + 2W = 4W + 18\]\[90\]\[90-18 = 4W = \]
\[72 = 4W\]\[W = 18\]

So 2 sides are 18cm and the other 2 are 27
