Taylor wants to find the perimeter of a rectangular playground.  The length of the playground measures (3x - 20) metres.  The width measures (2x + 4) metres.  What is the perimeter of the playground? 

 

The answer I got is:  5x - 16 metres

 

I don't understand why this is wrong, do you guys get any different answer? 

 

Thanks in advance :)
