Kapitoly: Area of the square, Area of the rectangle, Area of the circle, Area of the trapezoid, Area of the parallelogram, Area of the rhombus, Area of a regular n-gon, The surface of a sphere, The surface of a cube, The surface of a cuboid, Surface of a cylinder, The surface of a needle

By the volume of a rectangle we mean the size of the area occupied by the rectangle. A rectangle always has two and two sides of equal length; if all four sides are equal, it is a square. Denote the lengths of the two different sides by a and b. Then the area of the rectangle, denoted by S, is equal to

$$\Large S = a \cdot b$$

The following rectangle has side lengths equal to a = 5, b = 2, so the area of the rectangle will be equal to

$$\Large S = 5 \cdot 2 = 10$$
