Composite figure meaning that figure in the picture?

OpenStudy (anonymous):

yes

jabez177 (jabez177):

So first let's start off with the rectangle. To find the area of that we have to do Length x width

jabez177 (jabez177):

22 x 17

OpenStudy (anonymous):

374

jabez177 (jabez177):

In order for us to find the height of the Triangle we have to subtract 22 - 10 = what?

OpenStudy (anonymous):

12

jabez177 (jabez177):

Now same thing for the Triangle. To find the area of a triangle we have to do base x height so our height is 12, what is the base?

jabez177 (jabez177):

Of the triangle

OpenStudy (anonymous):

19 cm?

jabez177 (jabez177):

Yes! Now to get the area of a triangle we have to what?

OpenStudy (anonymous):

i got 228? is that correct? of doing 19 x 12

jabez177 (jabez177):

Yes. Now we divide 228 by 2

OpenStudy (anonymous):

114?

jabez177 (jabez177):

Yes. Now we do 114 + 374

jabez177 (jabez177):

And that will be your area. :)
