Area = w × l

w × l = 260
l + 5 = w + 2

do you get the first equation i posted ?

yes

okay

so to find w or y the equation would be y=x+2+5 or y=x+7

the y ?

opps other way round.

okay

solve for w (it will be a square root)

w is 13?

w²-3w-260=0
-(-3)±√[9-4(1)(260)]
----------------
2(1)
3±√[1049]
----------------
2

wait but shouldn't it be w + 2 = y - 5 ?

oh, tnx... my error

w × l = 260
l - 5 = w + 2
then,
w × l = 260
l = w + 7

w × (w + 7) = 260

13 is right

so the equation for w is w = l - 7 ?

so w=13

now, you nave to find l

20

l - 5 = w + 2
l - 5 = 13 + 2
l = 20
right !!

Thanks so much again!
