I already sliced the parallelogram into a triangle but I can’t figure out the area of them. Please help me

1 Foot squared.

Step-by-step explanation:

You started this out the best way, by dividing the parallelogram into triangles.

What you do after that is the standard way of finding the area of a triangle, which is base times height, divided by 2.

You take the base, in this case, 3, and multiply it by the height, which is 2/3, or 0.66. The result is 2.

You then take 2, and divide it by two, which comes out to 1 foot.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
