I think its like this: 144+b^2=400 b^2=266 b=16.3

yep, that's the height of the rectangle, and you just need to find the length and multiply.

how do u find the length

aacehmBest ResponseYou've already chosen the best response.0
well, think about it. If you cut that triangle off and put it back on, just on the other side, you're not changing the length at all

so its twelve inches the length

no, that's the length of the triangle you cut off. The length of the base of the parallelogram is the length.

Im realy confused inorder to find the area i just have to multiply 20 and 16 and get 320

aacehmBest ResponseYou've already chosen the best response.0
area of a parallelogram is base times height. You correctly found the height, using the pythagorean theorem. Now, you need to figure out which one the base is. (It's the one perpendicular to the height, and it's not 20). I was giving you a picture so you could see why this particular formula works.

yes, it's 32. I hope you understood how that worked.

so the area would be 16*32
