In this lesson, we will learn:

- The basic properties of the shape of the rectangle
- How to understand and calculate the perimeter of a rectangle
- How to understand and calculate the area of a rectangle

- A
**rectangle**is a 2D (two-dimensional) shape with 4 straight sides and 4 right angles (90°) - Each pair of sides (across from each other) are the exact same length

- A
**square**is a special type of rectangle where all side lengths are the same

- The
**perimeter**is the exact distance around the shape. - Perimeter is a 1D (one-dimensional) quantity
- It uses
**units**such as meters (m, cm, mm, km), miles (mi), yards (yd), or inches and feet (in and ft) - For
**rectangles**, the**formula**is written as: **P**= $(2 \, \times \, l) + (2 \, \times \, w)$_{rectangle}- Where $l$ is length, and w is width
- For
**squares**, the**formula**is written as: -
**P**= $4 \, \times \, s$_{rectangle} - Where $s$ is side length
- The
**area**is the space that is covered by the shape. - Area is a 2D (two-dimensional) quantity
- It uses
such as square meters (m__squared__units^{2}, cm^{2}, mm^{2}, km^{2}), square miles (mi^{2}), square yards (yd^{2}), or square inches and feet (in^{2}and ft^{2}) - For
**rectangles**, the**formula**is written as: **A**= $l \, \times \, w$_{rectangle}- Where $l$ is length, and w is width
- For
**squares**, the**formula**is written as: **A**= $s \, \times \, s \, = \, S^{2}$_{square}- Where $s$ is side length
