2.    Rectangle                   = ab

3.    Parallelogram               = bh

4.    Triangle                     = 1/2bh

5.    Circle                       = 3.1416 x r^2

6.    Trapezoid                   = 1/2 x (a+b)h

7.    Sphere                      = 4 x 3.1416 x r^2

where s = any side of the square

where l = length and w = width

where b = base and h = height

where b = base and h = height

where π= 3.14 and r = radius

where s= Surface area
