Answer:
Lets call the dimensions of the rectangle l and w. The new dimentions are 6l and 6w. The area of the first rectangle is lw. The area of the second rectangles is 36lw. 36lw/wl is the answer, and this is 36.
So 20%=0.2
so 20% more is same as
100%+20%=120%=1.2
equation could be
5.4 oz times 1.2
I don't know the answer sorry,
Let the first number be x and second number be y.

+ (3-2y) = 129
I believe this is what your looking for.
