A ramp is to be built using a 20 foot long board and an 18 foot long board. To make the ramp stable, the builders would like to add a third board to create a right triangle. How long should that board be, to the nearest hundredth of a foot? Justify.

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
