Question

A rectangular piece of paper has an area of 80 square sage draw a graph that shows the possible lengths and width of the paper

Answer 1

The graph is shown below

Explanation:

The area of a rectangle is computed as

A=L*W

Being W its width and L its length. Knowing the area is 80 square units, we have the relation

80=L*W

We can give W any value (except W=0) and compute the value of L by isolating it from the formula above

`L=(80)/(W)`

If W=1, we have L=80

If W=10, L=8

Some points to draw the graph are

(1,80) , (2,40) , (5,16) , (8,10) , (10,8) , (16,5) , (20,4)
