I never heard of decimals in this type of question before 5=4.5+c

I'm not sure what you're even trying to find since you didn't specify but if you are trying to find the value of 'c' :

0.5 = c

Reason:

5 - 4.5 = 0.5

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

true
