Well the rectangles appear  to be squares.....

 

Let their side length = 1

 

So     the top left shading is a triangle with a base of  6 and a height of 1

 

So its area  =(1/2) (6)(1)   = 3

 

The bottom right shading  has as base of 3  and a height of 1....so its area=  (1/2)(3)(1)  =3/2

 

And  the two  shaded square   each have an area  of 1  so their  combined   area   = 2

 

And the total area = the area of 12  squares with a side  of 1  =12

 

So

 

shaded area to  total area =    ( 3 + 3/2 + 2)  /12  =   ( 6.5)  /12   =  13/24

 

 

 

cool cool cool
