Subject: A brown bear's back paw prints measure 8' x 11'. How big would the bear be?

My class measured a cast of a brown bear's front and back paw prints taken 
recently in the area around our school. The front paws measured 7" x 8 1/2" and 
the back paws measured 8" x 11". We would liek to determine the approximate size 
of this bear. We know it is pretty big, but just how big is the question. Thanks 
for your help in this mat
