<PRE><B>Question 577414</B>
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?
:
Multiplier for 20% increase = 1.2
Multiplier for 20% decrease = .8
:
change in area:
c = L * W - 1.2L*.8W 
c = 1LW - .96LW 
c = .04 which is a 4% change in area, how much will depend on the actual dimensions you&#39;re dealing with here
