Answer:  The correct option is (B) 56 in².

Step-by-step explanation:  We are given to find the area of the trapezoid ABCD shown in the figure.

We know that

AREA of a trapezoid with length of the parallel sides a units, b units and height h units is given by

A=\dfrac{1}{2}(a+b)h.

For the given trapezoid ABCD, we have

a = AB = 6 in,  b = CD = 22 in   and    height, h = 4 in.

Therefore, the AREA of trapezoid ABCD is given by

A\\\\\\=\dfrac{1}{2}(a+b)h\\\\\\=\dfrac{1}{2}(6+22)\times4\\\\=2\times28\\\\=56~\textup{in}^2.

Thus, the required area of the trapezoid ABCD is 56 in².

Option (B) is CORRECT.

During the sixth grade lunch period, Paul asks every third student who enterd the lunchroom a survey question. Which question is
Neko [114]

Answer:

D

Step-by-step explanation:

You would have to eliminate A because the students have not yet been to other school districts especially if it's every third. You would also have to eliminate B because well, there really isnt any other place to eat but the lunchroom because otherwise it might pose a problem, and with C it can be difficult but again, if we were to try to change something the time they take really has no impact. D would have to be the correct answer because every third student will have various favorite lunch items and will ultimately tell the school that the gross macaroni that is like...unedible is bad and needs to be taken out...immediatley.
