In the polygon to the right, all adjacent edges are at right angles so that all its interior angles are either 90∘ or 270∘.  The four longer edges are equal in length, and all of the shorter edges are also equal in length. The area of the shape is 528.  What is the perimeter?

The figure is made up of 33 individual squares     each square is thus  528/33 = 16 units

     so each side of a square is 4         Each corner of the diagram is 9 square sides     so 36 sides of length 4 = 144 units  perimeter
