Answer asap it's important 30 points

√841

Step-by-step explanation:

You would use pythagorean theorem to solve this problem:

a² + b² = c²

a = 20 b = 21

20² + 21² = 400 + 441 = 841

√841

10000

step-by-step explanation: divide by 2,

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
