Alex and his friends are studying for a geometry test and one of the main topics covered is parallel lines in a plane. They each write down what they think it means for two distinct lines in a plane to be parallel: a. Rachel writes, ''two distinct lines are parallel when they are both perpendicular to a third line.''
b. Alex writes, ''two distinct lines are parallel when they do not meet.'' c. Briana writes, ''two distinct lines are parallel when they have the same slope.''
Analyze each definition, indicating if it is mathematically correct and if it has any drawbacks.

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
