So I don't know the equation but I know the answer.
Length: 170 ft.
Width: 100 ft.
Step-by-step explanation:
The perimeter (The length all around) is 270. You do the perimeter divided by two and add 35, because we know they are almost equal except for one side is 35 ft. longer, That is your length. You the take the perimeter minus the length to get the width.
N is the number of the Tshirt c is the cost the relationship between the cost and the number of the Tshirt is: 12n+3=c so if 1 is the number of the tshirt so the cost is 12.1+3=12+3=15 if n=2 c=12.2+3=24+3=27 and etc.....
