Calculate the man’s mass. (use pe = m × g × h, where g = 9.8 n/kg.) a man climbs a wall that has a height of 8.4 meters and gains a potential energy of 4,620 joules. his mass is about kilograms.

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

answer is b  

20

hope you get this one right.
