Finding Area and Perimeter on the Coordinate Plane

This video tutorial teaches how to find the area and perimeter of shapes on a coordinate plane. It covers calculating these measurements for rectangles and triangles, using base and height for area, and adding side lengths for perimeter. The tutorial also includes plotting points to form shapes and encourages viewers to review the material for better understanding.

How do you calculate the perimeter of a rectangle?

• Multiply base by height

• Add the length of all sides

• Divide the base by the height

• Subtract the width from the length
