Use the distance formula to calculate perimeter and area of polygons plotted on a coordinate plane.
Clarifications:

#### Essential Understandings

Concrete:

• Given a triangle or rectangle, determine the perimeter.
• Using a model of a triangle/rectangle and graph paper, identify the area and perimeter of the triangle/rectangle.
Representation:
• Identify the distance formula.
• Identify the formula for area.
• Using the identified formula and given coordinates, calculate the perimeter or area.
• Understand the following concepts and vocabulary: perimeter, area and formula.
General Information
Number: MAFS.912.G-GPE.2.AP.7a
Category: Access Points
Cluster: Use coordinates to prove simple geometric theorems algebraically. (Geometry - Major Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
