If we have two sides of a parallelogram in the ratio 5:4, then the other two sides must also be in the same ratio.
If the perimeter is 54, we can create the following equation regarding the length of each side

As our value for x is 3, and we know that the value for the larger side is 5x, we can simply plug in x to get the length of the larger side

(-2.5,2) i would say is about the approximate
To look for it just look at the lines intersecting
