# Ch 21: Finding Perimeter, Area & Volume

Review how to find perimeter, area and volume for the SAT Mathematics Level I subject test. Our online video lessons and quizzes can teach you to calculate these figures.

## Finding Perimeter, Area & Volume - Chapter Summary

Learn to calculate perimeter (the distance around the outside of a 2-dimensional figure), area (the amount of surface a 2-dimensional figure covers) and volume (the amount of space inside a 2-dimensional figure) through our SAT review lessons. Lessons in this chapter cover the following topics:

• Perimeter of quadrilaterals and irregular or combined shapes
• Perimeter of triangles and rectangles
• Area of triangles and rectangles
• Area of complex figures
• Area and circumference of circles
• Volume of prisms and pyramids
• Volume of cylinders, cones and spheres

Each lesson includes a video presentation, transcript and self-assessment quiz. The videos were designed by our team of professional mathematics educators to be brief yet comprehensive and engaging; however, if you learn better by reading than watching, you might opt to utilize the transcripts. Completing the short multiple-choice quizzes can help you measure your mastery of perimeter, area and volume, as well as familiarize you with the type of questions you'll find on the SAT Mathematics Level I subject test.

### SAT Mathematics Level 1 Objectives

The SAT Mathematics Level I subject test is intended for students who've completed at least one year of high school geometry and two years of high school algebra. Performing well on this exam could make you stand out among other college applicants, particularly if you're interested in a math-based program; this includes not just mathematics majors, but also programs in economics, engineering, science, technology and related fields.

You'll have an hour to complete the 50 multiple-choice questions on this test. Approximately 18-22% of the questions focus on plane Euclidean geometry, which could include questions on area and perimeter, while 4-6% center on 3-dimensional geometry, which might feature questions on volume.
