B) If a trapezoid has an area of 30 m2, a height of 3.2 m, and a bottom length of 11 m, what is the top length? Solve by using both the given formula and your formula from part (a).
If you have done your work correctly you should get the same value either way!
I Using A =
h(a+b)
2
to start:
Using your rearranged formula to start:

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

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

d is the answer
