Basically, when you double the two sides with the angle in between them, then you double the altitude, and when you double the altitude, you quadruple the area because.


A = 1/2 * b * h where:


b is the base = one of the included sides, and:


h is the altitude.


b is doubled and h is doubled to get:


A = 1/2 * 2 * b * 2 * h = 1/2 * 4 * b * h
