Let a equal the area of the original rectangle, l equal length and w equal width.
The original rectangle would have been
l*w= a
The modified rectangle would have been
(1.1l)*(1- (p)/(100))w=.88a This can be rewritten as lw(1.1)(1-p/100)=.88a Since a= lw, we can divide both sides of the function a if we substitute So we get (1.1)(1-p/100)=.88 (1-p/100)=.8 100-p=80 p=20

So the value of p is 20
