The formula for finding the perimeter of a rectangle is given by the sum of all four sides of the rectangle
The formula for finding the perimeter of a rectangle is given by the sum of all four sides of the rectangle. Since a rectangle has two pairs of equal sides, you can either add the lengths of both pairs or multiply the length of one pair by 2 and then add the length of the other pair.
Let’s say the length of one pair of sides is ‘a’ units and the length of the other pair is ‘b’ units. The perimeter (P) of the rectangle is given by:
P = 2a + 2b
This formula can also be written as:
P = 2(a + b)
In this equation, ‘a’ represents the length (the longer side) and ‘b’ represents the width (the shorter side) of the rectangle. By plugging in the values of ‘a’ and ‘b’, you can calculate the perimeter of any rectangle.
