Question

Jeanette wants to build a fence around her yard so that her dog can safely play. The width of the yard is one-fourth the length.

The perimeter of the yard is 60 feet.

What is the length and width of her yard?

Answer 1

P=L+L+W+W
P=L+L+1/4L+1/4L
P=2.5L
60=2.5L
L=60/2.5
L=24-------1

Now
P=2W+2L
2W=P-2L
2W=60-2(24)
2W=60-48
2W=12
W=12/2
W=6--------2
eq 1 and 2 gives length and width of Jeanette's Yard.
