Answer: A line has one dimension because it is made up of all points that extend infinitely in either direction.
Step-by-step explanation: A line is a straight one-dimensional geometric undefined figure which has no thickness. It extends infinitely in both directions. It has only length therefore, it is one dimensional.
20×1=20 20×2=40 20×3=60 20×4=80 20×5=100 20×6=120 20×7=140 20×8=160 20×9=180 20×10=200 (Only include this if the table is up to 12) 20×11=220 20×12=240
