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
