The rule of the perimeter of a rectangle is

[tex]P=2(L+W)[/tex]

L is the length

W is the width

Since the length of the field is 95 m

The perimeter of the field is 328 m

Substitute them in the rule

[tex]2(95+W)=328[/tex]

Divide both sides by 2

[tex]95+W=164[/tex]

Subtract 95 from both sides

[tex]\begin{gathered} 95-95+W=164-95 \\ W=69 \end{gathered}[/tex]

The width of the field is 69 m
