**drwls**, Sunday, August 14, 2011 at 2:55amLet a = the original square side length.

Reducing it by 40% leaves two opposing sides of the rectangle with length 0.6a. Let the other two sides' length be x

0.6a * x = a^2

x = a/0.6 = 5/3 * a

The other two side lengths must be inceased by 66.7% to keep the area the same.
