text: another math question this time i'll show you what i did so some people won't accuse me of cheating. here's th here's the problem: a rectangular pool is 8m longer than it is wide.a walkway 1m wide surrounds the pool .find the dimensions of the pool if the area of the walkway is 100m. this is how i tried to solve it:100=(w+8)(w+1)-(w)(w) =100=8wsq. +8x+1- 8xsq.=100=8x+1=100-1=8x+1-1=99=8x.then i divide 99 by 8 , but i always get the wrong answer.am i doing something wrong? please help. the area is 100 _m_? i don't think so - area is measured in square meters.  assuming that that's just a typo, the proper setup is 100=(w+2)(w+10)-w(w+8) -- the area of the pool+walkway minus the area of the pool. simplifying:  w²+12w+20-w²-8w=100 4w=80 w=20 l=28  edit: corrected typo
