Select the Rectangular Marquee Tool and starting from the left, draw a selection down around the 11th column, leaving 10 squares between the bottom of your selection and the bottom of the shape.

Leave 10 squares between the right edge of the selection and the right side of the shape. It should look like this:

Hold Shift again then count 10 columns of squares from the right side of the shape and draw a selection upward around the 11th column. Leave 10 squares between the top edge of the selection and the top of the shape. The third selection should look like this:

Leave 10 squares between the left edge of the selection and the left edge of the shape. When you're done it should like this:
