SOLUTION BY EDWIN:
hi, i was wondering if someone could help me solve this problem, and show me how to do it.
24. Gary has 1002 meters of fencing. He will use all the fencing to enclose a rectangular region that is four times as long as it is wide. One of the longer sides is bordered by a rive, so that side will not be fenced. What will be the dimensions of the region?
Please show work if possible. Thank you
Let this be the figure:
Let the two short sides each be x, and the long side 4x
Now since there are 1002 meters of fencing, if we add the
three fenced sides, we must get 1002, so
So the left and right sides are 167 meters each.
The long side is 4x, so that is 4(167) or 668 meters.
So the dimensions of the region are 668 meters by 167 meters.
