Answer 1

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 $(1.1l)*(1- \frac{p}{100})w=.88a This can be rewritten as lw(1.1)(1-p/100)=.88a Since a= lw, we can divide both sides of the function a if we substitute So we get (1.1)(1-p/100)=.88 (1-p/100)=.8 100-p=80 p=20$

So the value of p is 20
