The perimeter of a rectangle with a width x and a length that is twice the width

Sep 11th, 2015

Thank you for the opportunity to help you with your question!

The formula for perimeter of a rectangle is 2W + 2L

So the question tells us that the width is x and the length is twice the width or 2x.

Plug this into the first equation using W = x and L = 2x

2x + 2*(2x)  =  2x + 4x  =  6x

So the perimeter is 6x

Please let me know if you need any clarification. I'm always happy to answer your questions.
