Question

The perimeter of a square is proportional to the length of one side. A square with 10-inch sides has a perimeter of 40 inches. Write an equation relating the perimeter to the square of its side length. Does this graph represent a Proportional relationship?

Answer 1

The answer is yes.

Step-by-step explanation:

Yes, the length of a side of a square and the perimeter of the square are related proportionally.

Let the side of the square be a.

So, perimeter is given as =

a+a+a+a=4a

Or we can say =

4\times a=4a

We can see, that the perimeter is always 4 times the side length of the square.

Example:

Suppose the side of the square is 4 cm.

4\times4=16

So, perimeter = 4× 4 = 16
