Answer by srinivas.g(540) (Show Source): You can put this solution on YOUR website!
Let width be w cm
length = (w+14) cm
Diagonal = 34 cm
As per pythagorean theorem ,

mve 1156 to the right

divide with 2 each and every term on both sides

possible solution
either (w+30)= 0 or (w-16)=0
w=-30 or w= 16
w cannot be negative
hence w= 16 cm
length = 16+14 = 30 cm
Perimeter =
=
=
= 92 cm
Result : Perimeter = 92 cm
