This exercise focuses on calculating the area and perimeter of various shapes. The formulas for calculating the area and perimeter of geometric shapes are provided.

Imagine you have a piece of paper shaped like a square or a rectangle. You need to know how long each side is to find out how much space it covers and the area. For a rectangle, let's call the longer side the "length" and the shorter side the "width." To find the area, you multiply the length by the width.

To find the perimeter of a shape, you need to add up the lengths of all its sides. For a square, it's easy because all four sides are the same length, so you multiply one side by 4. For a rectangle, add the lengths of the two longer sides and the two shorter sides (2 times the length plus 2 times the width). For other polygon shapes like triangles, hexagons, or any shape with more sides, add the length of each side together.
