The scale on graph paper = 6 units.
Each of 6 units have 10 cm of space.
Length of hotdog is 9 units .
Let us break 9 units into two smaller parts.
9 units = 6 units + 3 units.
6 units = 10 cm and
3 units is the half of 6 units
Therefore 3 units = 10/2 = 5 cm.
Total length in centimeter of the hotdog = 10 cm + 5 cm = 15cm.
Therefore, 15 cm is the length, in cm of the actual hotdog.
