Area and perimeter of rectangles
Lessons
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
Notes:
- 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:
- Prectangle = (2×l)+(2×w)
- Where l is length, and w is width
- For squares, the formula is written as:
- Prectangle = 4×s
- 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 squared units such as square meters (m2, cm2, mm2, km2), square miles (mi2), square yards (yd2), or square inches and feet (in2 and ft2)
- For rectangles, the formula is written as:
- Arectangle = l×w
- Where l is length, and w is width
- For squares, the formula is written as:
- Asquare = s×s=S2
- Where s is side length
