Jill says 12.6¯¯¯ is less than 12.63. Explain her error. P. S: The line is supposed to be over the 6

Her error is 12.6¯¯¯  being more than 12.63

Step-by-step explanation:

The bar above the 6 means repeating so 12.6¯¯¯  would be 12.666 and 12.666 is more than 12.63.

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
