What are the differences between the metric and english systems of measurement?

All of the metric systems of measurement are base 10. What this means is that for every 10 of something, you get the next level of that. For instance, 10mm = 1cm.

What the United States uses for their measurement has random bases. For instance, 12 inches = 1 foot.

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
