A family moves into a new home and decides to fence 43,200 square feet (almost an acre of the backyard) to give its dog room to roam. If the area that will be fenced in is rectangular and the length is three times
as great as the width, how many linear feet of fence should the family buy?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
