The perimeter of a parallelogram is 72 meters. the width of the parallelogram is 4 meters less than it’s length. find the length and the width of the parallelogram?

The width would be x-4 and  

Length would be x  

Add all of the sides together  

(x-4)+(x-4) + x + x =72,

Which would come out

4x-8=72

Subtract 8 fro, 72 and you get 64  

Then divided 64 by 4

So. Width is 16 and length is 20 .         given (x-4)
