Refer to a rectangle Find an expression that represents its perimeter
on top of the rectangle. (Not sure what "on top of the rectangle" means)

Anyway:
A rectangle that is %28%282x-1%29%29%2F5 by 4%2F%28%283x%2B1%29%29
:
P = 2%28%282x-1%29%2F5%29 + 2%284%2F%283x%2B1%29%29
:
P = %28%284x-2%29%29%2F5 + 8%2F%28%283x%2B1%29%29
:
Arrange over a single denominator:
P = %28%283x%2B1%29%284x-2%29%2B5%288%29%29%2F%285%283x%2B1%29%29 = %28%2812x%5E2-2x-2%29%2B40%29%2F%285%283x%2B1%29%29%29 = %28%2812x%5E2-2x%2B38%29%29%2F%285%283x%2B1%29%29%29 = %282%286x%5E2-x%2B19%29%29%2F%285%283x%2B1%29%29%29
