You can answer this by using Pythagoras theorem. Okay, let me draw this first.
2 miles

^ Assume this is the rectangle. The long side is 2 miles while the shorter side is 1.5 miles.
So, to get the shortest distance, let's cut out a triangle from the rectangle.

^ 1.5 miles (I know the size is not logical,but imagine it please)
So to get the diagonal length =
=
= 2.5 miles
To calculate how much shorter = ( 2 miles + 1.5 miles) - 2.5 miles
= 3.5 miles - 2.5 miles
= 1.0 miles
