Perimeter and Areas of Rectangles and Squares

Perimeter and area are two important measurements for rectangles and squares.

The perimeter of a rectangle or square is the distance around the outside of the shape. To find the perimeter, you add up the lengths of all the sides.

For example, if you have a rectangle with a length of 5 units and a width of 3 units, the perimeter would be 5 + 5 + 3 + 3 = 16 units.

The area of a rectangle or square is the amount of space inside the shape. To find the area, you multiply the length by the width.

Using the same example as before, the area of a rectangle with a length of 5 units and a width of 3 units would be 5 x 3 = 15 square units.

For a square, since all four sides are the same length, you can find the perimeter by multiplying the length of one side by 4, and the area by squaring the length of one side.

For example, if you have a square with a side length of 4 units, the perimeter would be 4 x 4 = 16 units, and the area would be 4 x 4 = 16 square units.
