Answer:
The length is (36x -12)/(3x - 1) in
Step-by-step explanation:
Given data
Area A= [tex]36x -12 in^2[/tex]
Width W= [tex]3x - 1 in[/tex]
we know that the area A= length * width
i.e A= L*W
we can solve for the length by making it subject of the formula
L= A/W
L= [tex]\frac{36x -12}{3x - 1} in \\\[/tex]
