Yes, you are correct. To check: substitute your answers into this:
P = 2(length) * 2(width)
There's a rectangle.
On 1 side is 8 which is the Length side
I have to find out how long the width side is.
The whole perimeter has to equal 25 P=25
So if both length sides are 8 then that equals 16.
Now I have to see how much both width sides are
I did 25-16 and I got 9
then I divided 2 into 9 and got 4.5
w=4.5
Is this correct?

2*8 + 2*w = 25
16 + 2w = 25
2w = 9
w = 4.5 right
16 + 2w = 25
2w = 9
w = 4.5 right
