When you need to measure the boundaries of any closed geometric figure, it is calculated using the perimeter formula. With this perimeter calculator, it has become easy to calculate the perimeter of any geometrical figure. In the case of calculating the perimeter of a square, the formula is side *4. For a rectangle, you need to measure the height and width of the rectangle, and the formula for it is (width + height)*2. In the case of a circle, it’s 2** (diameter/2). There are different rules for calculating the perimeter depending upon the figure.
