From the information given,
current scale is
1 unit = 6 yds
Looking at the graph, a unit represents a small box on the graph. We can see that
length = 5 boxes = 5 units = 5 x 6 = 30 yds
width = 2 boxes = 2 units = 2 x 6 = 12 yds
We want to represent 30 yds by 12 yds with a scale of 1 unit = 3 yds
Considering the length, we have
3 yds = 1 unit,
30 yds = 30/3 = 10 units
Considering the width, we have
3 yds = 1 unit,
12 yds = 12/3 = 4 units
Thus, the new figure would have a length of 10 units and a width of 4 units
