## How to Calculate the Perimeter of a Rectangle?

If the length (L) and the width (W) of a rectangle are given, then the formula used to calculate the perimeter (P) of a rectangle is:

**Perimeter (P) = 2(L + W)**

**Solved Example:**

Find the perimeter of a rectangle whose length and width are 10 units and 6 units respectively.

**Solution:**

Substitute the values of length and width in the formula of the perimeter of a rectangle:

Perimeter = 2(L + W)

= 2(10 + 6)

= 2 × 16

= 32 units

Therefore, the perimeter of the rectangle is 32 units.

Now, use the calculator and find the perimeter of a rectangle whose length and width are as follows.

- Length = 20 units, Width = 14 units.
- Length = 15 units, Width = 7 units.
