Answer:
2(x-3)+2x=54
Step-by-step explanation:
Take the side length of the rectangle as x
For the perimeter we must have - as we also have 2 lots of a side that is 3 inches shorter than x.

The square root rounded up to the nearest integer, 6.
testing the values 1 through 6 for division into 36 we find factors of 36 which are : (1, 36)
(2, 18)
(3, 12)
(4, 9)
(6,6)
or in other words the sets would be : 1, 2 , 3, 4 , 6 , 9 , 12 , 18 , 36
The answer is b, 5x^2 + 24x + 1
