Aparallelogram is shown below:

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?

A) The formula for the area of a parallelogram is

.. A = bh

.. A = (9 ft)*(8/9 ft)

.. A = 8 ft^2

B) A diagonal line from A to C (or one from D to B) will divide the figure into two triangles, each with a base of 9 ft and a height of 8/9 ft. The area of each triangle is

.. A = (1/2)bh

.. A = (1/2)*(9 ft)*(8/9 ft)

.. A = 4 ft^2 . . . . . . . . . . . each is half the area of the parallelogram

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
