Rhombus Area = product of the diagonals Long Diagonal = side * sq root (2 + 2 * cosine (60)) Long Diagonal = 6 * sq root (2 + 2 * .5) Long Diagonal = 6 * sq root (3) Short Diagonal = 6 * sq root (2 + 2 * cosine (120)) Short Diagonal = 6 * sq root (2 + 2*-.5) Short Diagonal = 6 * sq root (1) Short Diagonal = 6 area = 6 * sq root (3) * 6 area = 36 * sq root (3) square inches Source: http://www.1728.org/quadrhom.htm
