#### Your students will use this collection of activity sheets to learn how to determine the area and perimeter of various geometric shapes using the information provided about their lengths, angles, etc. (correct formulas have been provided). These sets contain all introductory material, practice questions, reviews, longer exercise sheets, and quizzes. Answer keys have been provided for each set for instructors. The sets consist of multiple pages, so be sure you have printed all of them.

In this section we will look at two very important concepts and measures in the world of architecture and engineering. Perimeter is usually defined as the length around a shape. A common everyday measure of our perimeter is our waist. According to Lee Jeans, the average 10 year old boy has 27 inch waist. This means the distance around the average boys’ waist is 27 inches or just over 2 ruler sizes.

Area is a bit different than perimeter. While perimeter focuses on the outside of a shape, area focuses on what's on the inside of that shape. Since not all shapes are constant, there are different methods for measuring and calculating area of different shapes. The most common measures of area are for squares, rectangles, and triangles. This worksheet section will focus on these shapes. These worksheets and activities will help your students to learn how to understand and determine the height, length, circumference, perimeter, and/or area of various shapes using specific formulas and methods.
