How do you find the perimiter of a rectangle on a graph?

To find the perimeter of a rectangle on a graph, first identify the coordinates of its four corners (vertices). Calculate the lengths of the sides by finding the distance between two adjacent vertices, either horizontally or vertically. The perimeter is then calculated by adding the lengths of all four sides, or more simply, using the formula ( P = 2 \times (\text{length} + \text{width}) ). Ensure you accurately measure the length and width based on the scale of the graph.
