The length of the side of a square is increase by 50%. By what % is the area of the square increase.
\n" ); document.write( "------------------------------
\n" ); document.write( "If side = \"s\", area = s^2.
\n" ); document.write( "---
\n" ); document.write( "If s is increased by 50% you get (1.5s)
\n" ); document.write( "Area will be (1.5s)^2 = 2.25s^2
\n" ); document.write( "---
\n" ); document.write( "Increase = 2.25s^2-s^2 = 1.25s^2
\n" ); document.write( "---
\n" ); document.write( "% increase = (1.25s^2)/s^2 = 1.25 = 125% increase
