The answer will be similar as 7x20=140 and 7x2000=14000, the answers are the same but x100 as 140x100=14000
20x100=2000
So to graph you problem you should first consider that the one side of the bar is 150feet because it is in the other partitioned of the fence and the function of it would be 150(x) because the barn's area is calculated through it length time width. I hope this will help
