Draw a graph for the following. Is it a linear graph? Side of square (in cm) 2 3 3.5 5 6 Perimeter (in cm) 8 12 14 20 24

Let us draw the graph by taking side of a square ( c m ) on x -axis and perimeter ( c m ) on y -axis. Now, for a suitable scale, We take x -axis as 1 u n i t = 1 c m and y -axis as 1 unit = 4 cm . From the given data, the graph follows as below: Hence, it is a linear graph.
