Question 636347
<font face="Times New Roman" size="+2">

If you increase the perimeter of a square by 25%, you must increase each side by 25%, so now each side is 1.25 times the original measure.  The area of the original square would be *[tex \LARGE x^2] and the area of the new square is *[tex \LARGE (1.25x)^2].  Square 1.25 to get the factor of increase, subtract 1, then multiply by 100 to get the percentage increase.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
