Area and Perimeter of Rectangle

Calculate area and perimeter

A rectangle is a quadrilateral with four right angles. This program calculates both the area (space inside) and perimeter (boundary length) of a rectangle given its length and width.

📐 Formulas

Area

A = L × W

(square units)

Perimeter

P = 2(L + W)

(linear units)
