Instead of doing your problem for you, I'll do one exactly
like it so you can use it as a model to do yours exactly
the same way.  I'll do this one instead:

find area if length of a rectangle is (x+3) and its width is 9cm less than its
length

length = (x+3)
width = (x+3)-9 = x+3-9 = x-6
area = length∙width = (x+3)(x-6) = x²-6x+3x-18 = x²-3x-18

Now do yours the exact same way, step by step.  Only the numbers
are different.
