The formula for the perimeter of a rectangle is P=2(1+w).
Solve for I. thank you!!

Answer:
l = P/2 - w
Step-by-step explanation:
P = perimeter
w = width
====================================================
[tex]\mathsf{P=2(l+w)}[/tex]
[tex]\mathsf{\frac{P}{2} =l+w}[/tex]
[tex]\mathsf{\frac{P}{2} -w=l}[/tex]
[tex]\mathsf{l=\frac{P}{2} -w}[/tex]
