Area, Perimeter, and Circumference Definition
of Perimeter:
The distance around an enclosed area, such as a shape. To
Find the Perimeter of A Polygon:
By definition, the perimeter of a polygon is the sum of the lengths of all
its sides. So, Area L1
+ L2 + L3... = Definition
of Circumference: The distance around a circle. To
Find the Circumference of a Circle:
Circumference = Pi x Diameter of the Circle Definition
of Area: Area is the representation of the amount of space
enclosed by a figure. It is measured in units squared (i.e. inches
squared, meters squared, and so on. To
Find the Area of a Square:
If L is the length of one side of the square: Area = L x L = L2 To
Find the Area of a Rectangle:
Area = Width x Length To Find
the Area of a Parallelogram:
Area = Base x Height To Find
the Area of a Trapezoid:
Area = 1/2 (H) (a x b) To
Find the Area of a Triangle:
Area = 1/2 (base) (height) To
Find the Area of a Circle:
Pi x (radius) (radius) = Pi x radius2
