Question 364453
The width of a rectangle is 5 times its length. If the width of the rectangle is doubled, then doubled again, the new perimeter is which percent of the original perimeter? 
..
let length be x 
width = 5x
perimeter = 2*(L+W)
=2*6x
=12x
..
2*2*5x= 20x
length = x
...
perimeter = 2*(20x+x)
=42x
Ratio = 42x/12x
2.5 *100 = 250 %
