Rectangle
Area = L x wPerimeter = L + w + L + w = 2L + 2w
Triangles
Parallelograms
Perimeter = a + b + a + b = 2a + 2b
Area = b x h
Circles
Area = Circumference =
Irregular Shapes
oThe Area of a irregular shape is the area of the two rectangles added together.
oThe Perimeter of the irregular shape is equal to the sum of the segment around the outside of the figure
