if the length of a rectangle is increased by 20% and the width is decreased by 20% then what will be the change in area and how much?
\n" ); document.write( ":
\n" ); document.write( "Multiplier for 20% increase = 1.2
\n" ); document.write( "Multiplier for 20% decrease = .8
\n" ); document.write( ":
\n" ); document.write( "change in area:
\n" ); document.write( "c = L * W - 1.2L*.8W
\n" ); document.write( "c = 1LW - .96LW
\n" ); document.write( "c = .04 which is a 4% change in area, how much will depend on the actual dimensions you're dealing with here
\n" ); document.write( ":
