A = 2*a + 2*b

A = a * b

A = area

P = perimeter

a = side "a"

b = side "b"

A rectangle is a four-sided polygon, or quadrilateral, with opposite sides of equal length and all internal angles equal to 90 degrees. The properties of a rectangle include diagonals that are equal in length and bisect each other. The area of a rectangle can be calculated using the formula: Area = length * width, and the perimeter can be calculated as: Perimeter = 2 * (length + width). Rectangles are fundamental shapes in geometry and are commonly used in various applications in mathematics, design, and architecture.

The sides of the rectangle are, for example, a is 8 cm and b is 6 cm.

Thus

a = 8,

b = 6.

**perimeter of the rectangle:**

We use the formula

C = 2 * a + 2 * b

thus

C = 2 * 8 + 2 * 6

C = 28 cm

**area of the rectangle:**

We use the formula

A = a * b

thus

A = 8 * 6

A = 48 cm²
