Q. What is the formula to find the perimeter of a rectangle?

\newline

P=l \cdot w

\newline

P=l+w

\newline

P=2(l+w)

\newline

P=2 l+w

Definition of Perimeter: The perimeter of a rectangle is the total distance around the outside of the rectangle. To find the perimeter, we need to add up the lengths of all four sides. Since opposite sides of a rectangle are equal in length, we can use the formula that involves both the length ( $l$ ) and the width ( $w$ ) of the rectangle.
Incorrect Formulas: The formula for the perimeter of a rectangle is not $P = l \times w$ , because that would give us the area of the rectangle, not the perimeter.
Correct Formula: The formula for the perimeter of a rectangle is also not $P = l + w$ , because this would only give us the sum of one length and one width, not the total distance around the rectangle.
Correct Formula: The formula for the perimeter of a rectangle is also not $P = l + w$ , because this would only give us the sum of one length and one width, not the total distance around the rectangle.The correct formula for the perimeter of a rectangle is $P = 2(l + w)$ . This is because you have two lengths and two widths in a rectangle, and you need to add all four sides to get the perimeter.
