Questions fréquemment posées
How do you calculate the area of a rectangle?
Multiply the length by the width: S = a × b.
How do you find the diagonal of a rectangle?
Use the Pythagorean theorem: d = √(a² + b²).
What is the perimeter of a rectangle?
The perimeter is the sum of all sides: P = 2(a + b), or P = 2a + 2b.
