MATH Trouble HURRY!!!!

If the scale factor from a small figure to a large figure is given as a percent, how can you find the side lengths of the large figure from the side lengths of the small figure?
34 percent is 34/100
Set that equal to small/large
34/100=small/large, and solve for large.
Can you give us a specific problem? But let's say it was 50% bigger than the small and the small was a rectanglular box 10 X 8 X 4
Ok, then you multiply each number by .50 and add it to the numbers.
So, 10 X .50=5
8 X .50=4
4 X .50=2
Now add
10+5=15
8+4=12
4+2=6
So the bigger box sides are
15 X 12 X 6
For each small side ss and large side ls
ls = ss + ss * percent
ls = ss * (1 + percent)
