do you have graph paper with you?

- anonymous

Yea.

- anonymous

I plug in already those numbers in my graph.

ok. Choose a spot near the middle and draw arrows going down up, left, and right|dw:1442234895246:dw|

- anonymous

have you done that?

- anonymous

|dw:1442234952424:dw| i'm not sure.

now, |dw:1442234977397:dw|

- anonymous

then plot your coordinates

- anonymous

DOne.

- anonymous

nice job

- anonymous

I put those numbers in my graph already.

- anonymous

so do you know what shape that is?

it is a trapezoid, do you know the formula?

- anonymous

I think like that.

- anonymous

Yea

- anonymous

then plug in your side lengths to the formula and there is your area

- anonymous

what did you get as your final result?

- anonymous

Wait. How do i find the sides.

- anonymous

I just put dots in my graph to draw the trapezoid.

- anonymous

did you draw what you posted on the graph labeled with numbers?

- anonymous

No.

- anonymous

When i look at it, it looks like trapezoid.

- anonymous

But i don't know yet the exact numbers of those sides.

- anonymous

well we have D(-4,-4), E(4,-4), F(2,3) and G(-2,3) for our points so if we connect those points we get our sides. You can simply count the distance between these points if you draw this on graph paper

- anonymous

do you understand?

- anonymous

OK let, me check

- anonymous

tell me what you get

- anonymous

|dw:1442235773941:dw|

- anonymous

you actually do not need the last side length, as the formula for a trapezoid is h{(a+b)/2 where a and b are the bases, 4 and 8. To find the height, all you do is count the vertical distance from a to b.

- anonymous

I get it now. I find the area already. Thanks for helping LOL ^_^
