pleaassee help I will medal and fan parallelogram is shown below: A parallelogram ABCD is shown with DC equal to 3 feet and the perpendicular distance between AB and DC equal to 2 over 3 foot. Part A: What is the area of the parallelogram? Show your work. Part B: How can you decompose this parallelogram into two triangles? If this parallelogram was decomposed into two triangles, what would be the area of each triangle?

    halllloooo Area of a Parallelogram = (length of side) times (perpendicular height) in this case (length of side) = 3 feet (perpendicular height) = 2 over 3 feet

    it's a little confusing I suppose you could draw a line from B to D (which would make the parallelogram into two triangles) but in any case, it would simply divide the area in half so used the area you just found before and divide it by 2 :)
