<p>There is a figure with it.</p>

<p>I thought it was 1/32? But the answer is 1/64?</p>

<p>Lol, I just did this one a few hours ago. Say the smallest rectangle is 1 sqare unit and there are 2 of them. So, the rec. beside that one is 2 square units, and the above is 4, the on the left is 8, the one on top is 16, and the one on the left is 32. So add up 1+1+2+4+8+16+32=64 square units. So, since the rectangle is 1 square unit out 64, it is 1/64 of the entire figure</p>
