Exploring Area and Perimeter on the Coordinate Plane

The video tutorial explains how to find the area and perimeter of shapes on the coordinate plane. It outlines steps such as plotting points, connecting them to form shapes, and calculating side lengths. Examples include finding the perimeter and area of a rectangle, the area of a triangle using base and height, and the area of a hexagon by counting squares. The tutorial emphasizes understanding the geometric properties and using formulas for different shapes.

What is the first step in finding the area and perimeter on the coordinate plane?

• Plot the given points of the figure

• Connect the points to form the shape

• Use the lengths to find the perimeter and area

• Find the length of each side

How do you find the perimeter of a shape on the coordinate plane?

• Count the squares inside the shape

• Multiply the length by the width

• Divide the area by the height
