      Perimeter
                                  Square                  Triangles
       Rectangle
                          b
                          =
                          4                                  b            c

           L= 8cm                     L=6cm                       a
      P = 8 + 5 + 8 + 5          P = 6 + 6 + 6 + 6         P = a + b + c
         P = l + b + l + b     P = l + l + l + l
            = 2(l + b)            = 4l  or 4s
                                         
     Area
    Area is the space within the boundary 
      of a figure.
                               
                Area of parallelogram
                                 height
                                  base
          Area of parallelogram = base x height
                                      
     Area of a triangle

          b                 b                 b
      Area = ½ x base x height
                                 
     Area of trapezium

                     H
      Area of trapezium ABCD
            = area of ΔABC + area of ΔACD
            = (½ x BC x AH)  + (½ x AD x CK)
            = ½ x AH x (BC + AD)
            = ½ x height x sum of parallel sides
