quadratic word problem: a zamboni is resurfacing the ice on a rectangular rink 25 m wide by 40 m long. The operator starts at the centre of the rink and makes uniform rectangular passes over the...
surface gradually working outward in a concentric way. After only 10% of the surface is complete the machine breaks down. find the width of the remaining strip of unfinished ice surface.
The width is 23.71 and the length is 37.94 in approximation .The area of the unfinished ice surface is 90% of the entire rink,meaning it is 900m^2.
i tried , hope it helps
if you have a rectangle who's width is 25m and length is 40m, the area would be 1000m^2. If you subtract 10% of the area, he would have 900m^2 left. Divide that by 40m to get the width of 22.5m. I hope this helps, but I'm not quite so clear as to what the question is asking. Good luck!
