+130081 Half of the side of the square = sqrt (12^2 - 9.6^2) = 7.2 m
So the side of the square = 7.2 * 2 = 14.4 m = the base of the triangle
So......the area of the square = (14.4)^2 = 207.36 m^2
The area of the triangle = (1/2) ( 14.4) (9.6) = 69.12m^2
The trapezoid has bases of 14.4 m and 10 m and a height of 25.4 -14.4 = 11 m
So its area = (1/2) (11) ( 14.4 + 10) = (1/2) (11) (24.4) = 134.2 m^2
So....the total area = (134.2 + 69.12 + 207.36) m^2 = 410.68m^2
