Question

Draw a linear graph to show the perimeter side relationship of a square.

Answer 1

We know that the perimeter of a square is four times of its side. (i.e) P = 4a.
(Here, P = Perimeter and a = side)
For different values of a, the values of P are given in the following table.

a (in cm)	1	2	3	4
P = 4a (in cm)	4	8	12	16

Points: (1, 4), (2, 8), (3, 12), (4, 16).
Plot the above points. Join all the points. We get the linear graph of P = 4a.
