$Length \: of rectangle \: \\ =3x−4y+6z</p><p></p><p>$

$2× length =6x−8y+12z</p><p></p><p>$

$perimeter \\ =7x+8y+17z \\ =2× (length+Breadth)$

$2× breadth  \\ = Perimeter−2× length \\ </p><p>=(7x+8y+17z)−(6x−8y+12z) \\ =x+5z+16y</p><p></p><p>$

$breadth = \frac{x+5z+16y}{2} \\ = \frac{x}{2} + 8y + \frac{5}{2} z$
