Answer asap! i don't understand it at all! explain, too.

The quadrilateral has two parallel sides, so meets the definition of a trapezoid. The diagram shows its base lengths (the lengths of the parallel sides) to be 4 and 8, and the distance between those bases (the height) to be 6. The appropriate formula for the area (A) is

... A = (1/2)(b₁ + b₂)·h

Fill in the numbers and do the arithmetic.

... A = (1/2)(4 + 8)·6

... A = (1/2)·12·6

... A = 6·6 = 36

The area of the trapezoid is 36 square units.
