+240 I've done the rest of the worksheet, but I'm stumped on this one. Can anyone help me?
+592 If you look at the 4 small triangles, two that are shaded and two that are not, you will notice that they have the same base and height, which means they have the same area. We can then swap the shaded witht he unshaded, so the two center triangles are shaded, and the two outer right triangles are not, and because the two iscosolese triangles sum up to 2/3(I'm asuming that the bases of the square are split into 1/3 and 2/3) and they are both shaded, the answer is $\boxed{\frac23}$
