The function used to find the perimeter of a square, represented by y, given the length of a side, represented by x is: y = 4x
Solution:
Let "y" be the perimeter of square
Let the length of side be "x"
From given,
The perimeter of a square is the product of four and the length of a side
Which means,
[tex]\text{Perimeter of square } = 4 \times \text{ length of side }[/tex]
Substituting the given variables,
[tex]y = 4 \times x\\\\y = 4x[/tex]
Thus perimeter of square is y = 4x
