Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, you simply add up the lengths of all its sides.

The formula for the perimeter of a rectangle is: [ P = 2(l + w) ]

Where:

• ( P ) = Perimeter
• ( l ) = Length
• ( w ) = Width

Given that the length of the rectangle is 5 units and the width is 3 units, you can substitute the values in the formula: [ P = 2(5 + 3) ] [ P = 2(8) ] [ P = 16 ]

So, the perimeter of a rectangle with length 5 and width 3 is 16 units.
