Question

Consider a square whose size varies. Let s s represent the side length of the square (in cm) and let P P represent the perimeter of the square (in cm).

Write a formula that expresses P in terms of s.

Answer 1

P = 4s

Explanation:

The perimeter of a geometric shape is simply the sum of all its sides length. Since the shape in question is a square, which means that all of the four sides have the same length 's', the perimeter can be expressed by:

`P = s+s+s+s\\P=4s`

For any value of 's', the formula above expresses the perimeter 'P' as a function of 's'
