United Weavers of America Charlize Flint Geometric Modern Area Rugs, Off-White

I ordered the 3' x 5' rug because I needed a small area rug. What arrived was a runner. The label on the back of the rug indicates it's 2'7" x 4'2". That is a VERY big difference. The only way to know this when ordering on line is to go to the last line of the specifications where it says "assembled product dimensions" 50.00 x 31.00 x 0.47 Inches. The same goes for all the sizes. Why can't the ACTUAL measurements be indicated in the place where you choose the size. Or, have a note "for actual dimensions see the bottom of specifications" and have the buttons say "approximately" with the sizes.
