Question

Draw a graph for the following.
(i)

Side of square (in cm) 2 3 3.5 5 6

Perimeter (in cm) 8 12 14 20 24

Is it a linear graph?

(ii)
Side of square (in cm) 2 3 4 5 6

Area (in cm2) 4 9 16 25 36

Is it a linear graph?

Answer 1

Answer:

The graphs for the question above are attached in the image

Step-by-step explanation:

The two graphs, Perimeter against side of square and Area against side of square can be plotted using these values as the format

Perimeter against side of square:

Side of square (in cm) 2    3    3.5    5      6

Perimeter (in cm)        8    12   14     20    24

These are the coordinates that you will use for plotting the graph:

(2,8) , (3,12) , (3.5,14) , (5,20) , (6,24)

Perimeter against side of square:

Side of square (in cm)       2     3     4    5      6

Area               (in cm²)       4     9    16   25   36

These are the coordinates that you will use for plotting the graph:

(2,4) , (3,9) , (4,16) , 5,25) , (6,36)

Answer 2

I) This is a linear graph.

ii) This is not a linear graph.
