The length of the longer side of rectangle r is 10 percent more than the length of a side of square s. The length of the shorter side of rectangle r is 10 percent less than the length of a side of square s. What is the ratio of the area of rectangle r to the area of square s? Express your answer as a common fraction.

 

Any help would be much appreciated!  smiley

s= square side

then areas ratio becomes:

 

(s+.1s)(s-.1s) / (s * s) =

s^2 - .01s^2) / s^2

 

(1- .01)/1 = .99/1 =  99/100
