GK is parallel to HJ and find the perimeter

OpenStudy (btaylor):

Set up a proportion.

OpenStudy (anonymous):

\[\frac{ x-2 }{ 9 } = \frac{ 4 }{ x+3 }\]

OpenStudy (anonymous):

OpenStudy (anonymous):

No, it wouldn't. Hold on.

OpenStudy (btaylor):

Almost. You need the ratio of the small (x-2) to the whole (x-2+9, or x+7) for each part.
