When calculating simple interest, what must you do if you want to invest for months or weeks instead of years?
a.
simple interest only pays yearly, so you should find another investment.
b.
the simple interest calculation does not use those units, so you should just calculate as normal.
c.
the units have changed, so the interest formula switches to i·t=p·r.
d.
interest rates are annual, so you must convert the units into years.

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
