Answer 1

Finding the Length of a Square Given its Perimeter

To find the length of a side of a square when the perimeter is given, we can use the formula for the perimeter of a square, which is four times the length of one side.

Let's denote the length of one side of the square as s. The formula for the perimeter of a square is:

Perimeter = 4s

In this case, the perimeter is given as 20 cm. We can substitute this value into the formula and solve for s:

20 = 4s

To find the value of s, we can divide both sides of the equation by 4:

20/4 = s

Simplifying the equation gives us:

5 = s

Therefore, the length of one side of the square is 5 cm.

Solution:

The length of one side of the square is 5 cm.
