Rectangle Formulas

1. Area of Rectangle Formula

Area = l \times b

The area is the product of length (l) and breadth (b).

Perimeter = 2 (l + b)

The perimeter is twice the sum of length and breadth.

d = \sqrt{l 2 + b 2}

The diagonal (d) is the square root of the sum of squares of length and breadth.

l = \frac{Area}{b}

If the area is known, length (l) is area divided by breadth (b).

b = \frac{Area}{l}

If the area is known, breadth (b) is area divided by length (l).
