2(l+b)=130
l+b=65------(1)
l=65-b----(2)
lb=1000-----(3)
put(2)in(3)
(65-b)(b)=1000
b^2-65b+1000
b^2-25b-40b+1000=0
b(b-25)-40(b-25)=0
b=40m or b=25
put value of b in (2)
l=65-40 | l=65-25
l=25 | l=40
l+b=65------(1)
l=65-b----(2)
lb=1000-----(3)
put(2)in(3)
(65-b)(b)=1000
b^2-65b+1000
b^2-25b-40b+1000=0
b(b-25)-40(b-25)=0
b=40m or b=25
put value of b in (2)
l=65-40 | l=65-25
l=25 | l=40
