Michael wants to find the length of the shadow of a tree. he measures the height of a fencepost and the length of the shadow it casts. the fencepost is 3.5 feet tall, and its shadow is 10.5 feet long. next, michael measures the height of the tree, and finds it is 6 feet tall. how long is the shadow of the tree?

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
