This document provides formulas for calculating the areas and perimeters of basic shapes like rectangles, parallelograms, rectangular prisms, trapezoids, circles, and triangles. For rectangles, it gives the formulas for area as length times width and perimeter as 2 times length plus 2 times width. For parallelograms, the area formula is base times height. It also lists volume, area, diameter, circumference, and triangle area formulas.
