# The Answers to Practice and Homework Lesson 11.3

Practice and homework lessons are a great way to review material that has been taught in the classroom and prepare for upcoming tests and quizzes. Lesson 11.3 is a particularly important review of concepts that are commonly tested. Knowing the answers to this lesson is essential for success in any math class.

## The Concept of Perimeter

The first part of Lesson 11.3 focuses on the concept of perimeter. Perimeter is a measure of the distance around a two-dimensional shape. The perimeter of a shape is equal to the sum of the lengths of each side. To calculate the perimeter for a square, for example, one needs to add up the lengths of all four sides.

## The Concept of Area

The second part of Lesson 11.3 focuses on the concept of area. Area is a measure of the space inside a two-dimensional shape. The area of a shape is equal to the product of the length and width of the shape. The area of a square, for example, can be calculated by multiplying the length of one side by the width of another side.

## The Relationship Between Perimeter and Area

The third part of Lesson 11.3 explores the relationship between perimeter and area. The relationship is simple: as the perimeter of a shape increases, the area of the shape increases as well. This is because as the perimeter of a shape increases, the length of each side also increases, leading to an increase in the total area of the shape.
