Question

Bob fenced in his backyard. The perimeter of the yard is 22 feet, and the length of his yard is 5 feet. Use the perimeter formula to find the width of the rectangular yard in inches:
P = 2L + 2W.

Answer 1

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

$P=2(L+W)$

we have

$P=22\ ft$

$L=5\ ft$

substitute in the formula and solve for W

$22=2(5+W)$

Divide by 2 both sides

$11=(5+W)$

Subtract 5 both sides

$W=11-5=6\ ft$

Convert feet to inches

Remember that

1 ft= 12 in

$6\ ft=6*12=72\ in$
