Got stuck on this one word problem that involves circles, rectangles and both their areas. I did not know where this would go so I put it here. I have a picture of the problem as an attachment also.
Now about the problem. I had no trouble starting off with my picture and I defined my variables as:
l-8= length of the yard(not border)
w-8= width of the yard(not border)
l= length of flower border
w= width of flower border
After that I wrote down my two equations:
lw-667= 548 and (l-8)(w-8)= 1215
I am stuck right now as I do not know what to do after simplifying both equations to:
lw= 1215 and lw-8l-8w+64=1215
Do I do substitution from here and then what? I do not want an answer I would be happy if someone could explain step by step what to do and how to get my solution for the two questions asked in the problem. This is as far as I got and the rest is confusing to me. Thank you in advance.
