If the width of a rectangle is decreased by 10% and the length is increased by 10%, find the percent change in the area of the rectangle.


Can someone please help? Thanks!
 
Sorry Denis, but all I wanted was help getting started on these problems (like hints). I was not expecting them being fully done (but thank you Soroban). :rolleyes:
