-- The area of the long skinny piece on top is (6 x 33) = 198
-- The length of the dotted line between the top and bottom pieces is (33-21) = 12
-- The area of the bottom piece is (12 x 15) = 180
-- The area of the whole thing is (198 + 180) = 378
-- The perimeter of the whole thing is (33 + 6 + 21 + 15 + 12 + 15 + 6) = 108

To find the area and perimeter of a shape, divide it into simpler rectangles and triangles, calculate each area and add them together for the total area. The perimeter is found by adding the lengths of all the sides. This method makes it easier to solve complex geometric problems.
