The area of a trapezoid is given by the formula a=h/2(a+b)?

the formula would be A=(a+b)/2 x h

Step-by-step explanation:

Well, the formula for the are of a trapezoid is not A=h/2(a+b).

It is actually:

A = (a + b) / 2 * h.

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
