Question

The perimeter of a square is the product of four and the length of a side. Which of the following funct

used to find the perimeter of a square, represented by y, given the length of a side, represented by x

Answer 1

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,

`\text{Perimeter of square } = 4 * \text{ length of side }`

Substituting the given variables,

`y = 4 * x\\\\y = 4x`

Thus perimeter of square is y = 4x
