2. The perimeter of a triangle is 100 feet. The longest side is two times the length of the shortest side and the other side is 20 feet longer than the shortest side. Find the lengths of the three sides of the triangle.

Let a, b, c be the sides of the triangle, where
a is the longest and c is the shortest.
a%2Bb%2Bc=100
a=2%2Ac and
b=c%2B20 so
2%2Ac%2Bc%2B20%2Bc=100
4%2Ac%2B20=100
4%2Ac=100-20
4%2Ac=80
c=20
b=20%2B20=40
a=2%2A20=40
