Answer:
B
Step-by-step explanation:
[tex]P=2L+2W[/tex]
[tex]P-2L=2W[/tex] (Subtract 2L from both sides of the equation)
[tex]2W=P-2L[/tex] (Symmetric Property of Equality)
[tex]W=\frac{P-2L}{2}[/tex] (Divide both sides of the equation by 2)
[tex]W=\frac{P}{2} -\frac{2L}{2}[/tex] ("Split" the fractions)
[tex]W=\frac{1}{2}P-L[/tex] (Simplify)
