D and B?

OpenStudy (acxbox22):

correct ;)

OpenStudy (igreen):

No..that's incorrect.

OpenStudy (winsteria):

They both equal 62 but I could be wrong?

OpenStudy (igreen):

This is one way

OpenStudy (igreen):

This is another

OpenStudy (winsteria):

Okay

OpenStudy (igreen):

For the first way, what are the sides of each rectangle?

OpenStudy (winsteria):

4 and 3?

OpenStudy (igreen):

Yes, that's for one, what's the other?

OpenStudy (winsteria):

7 and 9? @iGreen

OpenStudy (acxbox22):

sorry lag...but how is it wrong?

OpenStudy (winsteria):

I thought I was correct lol @iGreen

OpenStudy (igreen):

No..that side isn't 9..that's the length of the entire side.

OpenStudy (igreen):

To find the length of that side, subtract 9 - 4
