The perimeter of this rectangle is 30 units. How long is the longer side? a. 24 units
b. 9 units
c. 5 units
d. 6 units​

b. 9 units

Step-by-step explanation:

30/2 -6 = 15-6 = 9

9

Step-by-step explain

6+6=12

12+x=30

30-12=18

18/2 =9

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
