Area and perimeter are two different mathematical concepts used to describe the characteristics of shapes, but they represent different properties.

Area refers to the measure of the surface enclosed by a shape. It is expressed in square units (such as square centimeters or square meters). To find the area of a shape, you need to multiply the length of one side by the length of an adjacent side. For example, the area of a rectangle is found by multiplying its length and width. The area represents the amount of space inside the shape.

On the other hand, perimeter refers to the sum of all the sides of a shape. It is expressed in units of length (such as centimeters or meters). To find the perimeter of a shape, you need to add up the lengths of all its sides. For example, the perimeter of a rectangle is twice the sum of its length and width. The perimeter represents the distance around the shape.

In summary, while area measures the surface enclosed by a shape, perimeter measures the distance around the shape.
