Plot the points A(0, 0), B(3, 0), C(2, 9), and D(1, 9) on a coordinate plane. Draw the segments AB, BC, CD, and DA. What is its area?
it is trapezoid:

if
and
then
we need a lenght and
a distance between A and B ....=>...a lenght
a distance between C and D....=>...a lenght
now to find a lenght we need a distance to
then
