**Basic**Created by: CK-12

## Introduction

Now that we have explored triangles, quadrilaterals, polygons, and circles, we are going to learn how to find the perimeter and area of each.

### Chapter Summary

## Summary

This chapter covers perimeter and area of all the basic geometric figures. Perimeter and area are compared and calculated for rectangles, parallelograms, triangles, and then for composite shapes of those figures. The chapter then branches into perimeter and area for other special geometric figures, namely trapezoids, rhombuses, and kites, as well as similar polygons. The chapter continues with the circumference of circles and arc length followed by the area of a circle and the area of sectors and segments. The chapter wraps up with area and perimeter of regular polygons.
