If the longer side of yellow = y, and the longer side of the orange = o, // yellow+pink+green area = 3 x orange) y * o = 3 (3 * o) y = 9 Side of square = 9+

If the longer side of yellow = y, and the longer side of the orange = o, // yellow+pink+green area = 3 x orange) y * o = 3 (3 * o) y = 9 Side of square = 9+3 = 12. So area is 144.
