<h3>Perimeter of a Square</h3>

The perimeter of a square is given as the sum of the total sides in the square or 4 multiplied by the side length of the square since they all have equal sides.

Mathematically, this can be written as

P = 4 *L\\P = 4l\\

  • L = side length

In this given question, the side length is equal to x and the perimeter of the square is given as 24.2in.

Let's substitute the values

P = 4L\\24.2 = 4L\\but l = x\\24.2 = 4x\\x = 6.05in

The side length of the square is equal to 6.05in
