Question

In the equation y = 2x, y represents the perimeter of a square.What does x represent?Ahalf the length of each sideBthe length of each sideСtwice the length of each sideDtwice the number of sides

Answer 1

Given:

An equation that represents the perimeter of a square:

`y=2x`

To find:

What x represents.

Solution:

It is known that the perimeter of the square is equal to four times the side of the square.

Let the side of the square be s. So,

`\begin{gathered} y=P \\ 2x=4s \\ x=(4s)/(2) \\ x=2s \end{gathered}`

Therefore, x represents twice the length of each side.
