PERIMETER, CIRCUMFERENCE, AND AREA

In this unit, you will determine perimeter, find circumference, and calculate area of two-dimensional shapes. Perimeter is the distance around polygons and circumference is the distance around circles. Area is the region that any two-dimensional shape covers and is measured in square units. You will extend your knowledge of area by finding the area of circle sectors and the area of composite shapes.
