# GEOM 1 | Lesson 1: Developing Formulas for Area of Multiple Shapes

## Overview

### Learning Intentions (Objectives)

a) Students will develop the formulas for the area of a rectangle, parallelogram, triangle, trapezoid, and circle by establishing how they are developed from one another.

b) Students will apply the formulas to solve for areas of these shapes.

### Rationale (Diagnostic Results)

You often do not remember common geometric formulas such as the area of a trapezoid, parallelogram, circle, etc.
