Side of square(in cm) | 2 | 3 | 3.5 | 5 | 6 |
Perimeter (in cm) | 8 | 12 | 14 | 20 | 24 |
Side of square(in cm) | 2 | 3 | 4 | 5 | 6 |
Area (in cm2) | 4 | 9 | 16 | 25 | 36 |
Is it a linear graph?
(i) Choosing a suitable scale,
For \(x-axis\), \(1\) unit = \(1\) cm and for \(y-axis\), \(1\) unit = \(4\) \(cm\)
We can represent the side of a square on \(x-axis\) and the perimeter of that square on \(y-axis\).
A graph of the given data is drawn as follows.
It is a linear graph.
(ii)Choosing a suitable scale,
For \(x-axis\), \(1\) unit = \(1\) cm and for \(y-axis\), \(1\) unit = \(4\) \(cm^2\)
We can represent the side of a square on the \(x-axis\) and the area of that square on \(y-axis\).
A graph of the given data is as follows.
It is not a linear graph.
