isuru let kesh finish...?

anonymous · Answer

let l=w+4
therefore,perimeter=2xlxw
                                   =2(w+4)w
                                   =2(w^2)+8w
since we already know that perimeter=34
we have 2w^2 +8w=34
dividing throughout by 2;
w^2+4w-17=0
solve the quadratic using the quadratic formula to obtain the value of w
