Here is ONE way .....calculate the area of the red rectangle ...then subtract the 4 triangles

 

5 x4     -  2 * 1/2 (1 * 3) -  2 * 1/2 (4 * 1) =   20 - 3 - 4 = 13 units 2             as TA  posted !

Hey there, Guest!

 

The answer is 13 units squared.

You have to count and then do some division.

 

Hope this helped! :)
