![]() If the perimeter and the length of a rectangle are known, the width can be calculated using the formula: Width = P/2 - l, where l = length of the rectangle and w = width of the rectangle, and P = perimeter of the rectangle.In that case, we use the following formulas: There are other scenarios where the perimeter of a rectangle is known and the other dimensions are missing. Perimeter of a rectangle = 2(l + w) where 'l' is the length and 'w' is the width of the rectangle. We know that the formula used to calculate the perimeter of a rectangle is: Step 3: After solving the equation, the value of the perimeter is calculated.Step 2: The respective values of length and width are substituted in the formula.Step 1: To calculate the perimeter of a rectangle, the length and width should be known.The three steps listed below are helpful to find the perimeter. We can calculate the perimeter of a rectangle in three simple steps. How to Find the Perimeter of a Rectangle? ![]() The formula for the area of a rectangle is, Area of rectangle = length × width On the other hand, the area of a rectangle is the total space occupied by the rectangle and is expressed in square units like, cm 2, inches 2, and so on. The perimeter of a rectangle formula = 2(length + width). There is no direct relationship between the area and perimeter of rectangle because the perimeter of a rectangle is the total length of its boundary and is expressed in linear units like cm, inches, and so on. Relationship Between Area and Perimeter of a Rectangle However, in case of a square, all the sides are of equal length. The perimeter of rectangle formula is different from the perimeter of a square because only the opposite sides of a rectangle are equal. ![]() However, the perimeter of a square formula is expressed as, perimeter of a square = 4 × s where 's' is the side length.
