An 8.5-by-11-inch piece of paper is folded in half repeatedly (never being unfolded), each time shortening what was then the longer side. What is the length of the longest side, in inches, immediately after the second fold? Express your answer as a decimal to the nearest tenth.

The first fold results  in  the side of 11  being divided in half....so....we have the the dimensions

8.5  x  5.5

 

The second fold results in the side of 8.5 being divided in half...so...we have the dimensions

4.25 x  5.5

 

So....the longest side is   5.5 in
