Choice B

Step-by-step explanation: Hello!

To find the length of KL, we will need to use the distance formula.

The distance formula is \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}.

We are given K(4, 5) and L(4, -2), and we can find the distance between these two points through substitution.

\sqrt{(4-4)^{2} +(-2-5)^{2}}

\sqrt{(0)^{2} +(-7)^{2}}

\sqrt{(7)^{2}} = \sqrt{49} = 7

Therefore, the length of KL is 7 units, choice B.

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
