The perimeter of a triangle is 80 meters. The first side is twice the second. The third side is 5 more than the first. Find the length of each side.

Step-by-step explanation:

a+b+c=80

a=2b

c=5a

c=5*2b=10b

2b+b+10b=80

13b=80

b=80/13 m

a=2*80/13=160/13

c=10b=800/13

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
