Question

how do you find the area of a trapezoid?

Answer 1

Average length of the bases times the height.

Answer 2

how do you average the length?

Answer 3

add them and divide by two?

Answer 4

\(A = \dfrac{(B + b)h}{2} \)

Answer 5

Yes, you are correct.

Answer 6

and then multiply that by the height?

Answer 7

Yes.
Notice that after you find the average of the bases, you must multiply by the height. The height is the perpendicular distance between the bases, with length h in the drawing. Don't use the lengths of the slant sides.
