Question

Which equation represents the relationship between the side length, x, and the perimeter, y?

Answer 1

depends on the geometric shape

Explanation:

for a square or rhombus it is 4*x=y

for a rectangle or parallelogram it is 2(x+b)=y where b is the other side.

Answer 2

The equation representing the relationship between the side length x and the perimeter y is y = 4x.

What is the equation that represents the perimeter?

To find the equation that represents the relationship between the side length x and the perimeter y of a square, we can use the formula for the perimeter of a square, which is P = 4x, where P is the perimeter and x is the side length.

In this case, the side length (x) and perimeter (y) values are given in the table. Let's use the values from one of the points, for example, (4.5, 18):

P = 4x

18 =
`4 * 4.5`

Now, we can generalize this equation using the variables x and y:

y = 4x
