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.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
