## Rectangle Perimeter

### The perimeter of a rectangle is the total distance around its outer boundary

The perimeter of a rectangle is the total distance around its outer boundary. It can be calculated by adding up the lengths of all its sides.

For a rectangle, there are two pairs of equal sides. Let’s assume the length of one pair of opposite sides is denoted by “l” and the length of the other pair is denoted by “w”.

To find the perimeter, you need to add the lengths of all four sides. Since there are two pairs of equal sides, you can either add the length of one pair twice or add the lengths of all four sides separately. Both methods will give you the same result.

Method 1: Adding one pair twice

Perimeter = 2l + 2w

Method 2: Adding all four sides separately

Perimeter = l + w + l + w

Either way, the result will give you the perimeter of the rectangle.
