The document provides formulas and examples for calculating the perimeter and area of various geometric shapes, including: - Rectangle: Area = length x width, Perimeter = 2x length + 2x width - Triangle: Area = 1/2 x base x height - Irregular shape: Area is the sum of the individual areas of its parts. Perimeter is the total distance around the shape. - Parallelogram: Area = base x height - Trapezoid: Area = (base 1 + base 2) x height / 2 - Rhombus: Area = 1/2 x diagonal 1 x diagonal 2 It then provides examples of calculating areas for various shapes using these formulas.
