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?
+36916 The figure is made up of 33 individual squares each square is thus 528/33 = 16 units2
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
