Answer:
[tex]W=(\frac{P}{2}-L)\ yd[/tex]
Step-by-step explanation:
we know that
The perimeter P (in yards) of a soccer field is
[tex]P=2L+2W[/tex]
where
L is the length in yards
W is the width in yards
Solve the equation for the width W
That means -----> isolate the variable W
Subtract 2L both sides
[tex]P-2L=2W[/tex]
Divide by 2 both sides
[tex]W=(\frac{P}{2}-L)\ yd[/tex]
