My rectangle is 3 inches wider than
Earl’s rectangle. The length of my
rectangle is 3 times its width.
The perimeter of my
rectangle is half the perimeter
of Polly’s square. The width of
my rectangle is 4 inches.
My square has a
perimeter of 36
inches.
What is the perimeter of
Mac O’Roaney’s rectangle?

I’ll start with Polly’s fact. I can
