Add the entire height of the rectangle and multiply by the width(10).
(9+16.6+14)*10=396
Triangles are (1/2)bh and there are two of them.
2(1/2)*9*14=126
Add 126+396=522 m^2
we have 3 rectangles and 2 triangles
rtop rectangle   area   10*9           =     90
middle   ..          area  10*16.6      =   166
bottom  ....                  10* 14        =   140

left triangle               0.5*9*14       =     63
right triangle                                  =     63

TOTAL area = sum of these         =     522 m^2
