Answer:

The width of the rectangular yard is 72 inches

Step-by-step explanation:

Let

L -----> the length of the yard

W ----> the width of the yard

we know that

The perimeter is equal to

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

we have

[tex]P=22\ ft[/tex]

[tex]L=5\ ft[/tex]

substitute in the formula and solve for W

[tex]22=2(5+W)[/tex]

Divide by 2 both sides

[tex]11=(5+W)[/tex]

Subtract 5 both sides

[tex]W=11-5=6\ ft[/tex]

Convert feet to inches

Remember that

1 ft= 12 in

[tex]6\ ft=6*12=72\ in[/tex]
