the smallest possible measurement of the width is 14 feet

step-by-step explanation:

width of parallelogram is 'w'

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

the correct answer is c
