Make them into a bunch of triangles with interior lines. Triangles do not change shape once the length of the three sides is fixed. (side,side,side --->congruent)
For example once you draw one diagonal in a square, it is split into two triangles and will not squish into a parallelogram.
This is not just theory. It is how you build bridges and buildings.

mIA, don't tag new questions on the end of other problems, start a new post.
percent means per centum or per hundred
so whatever the percentage number is, divide it by 100, then reduce to lowest terms if needed.
e.g.
35% = 35/100 = 7/20
7% = 7/100
12.3% = 12.3/100 = 123/1000
