**Bosnian**, Tuesday, November 15, 2011 at 10:35pmW = Width

L = Length

A = Area

W = L - 6

A = W * L

135 =( L - 6 ) * L

135 = L ^ 2 - 6 L

The exact solution are :

L = - 9 cm

and

L = 15 cm

The length can't be negative so:

L = 15 cm

W = L - 6

W = 15 - 6 = 9 cm

A = W * L = 15 * 9 = 135 cm ^ 2

P. S.

If you don't know how to solve equation:

135 = L ^ 2 - 6 L

Go on:

When page be open in rectangle type:

solve 135 = L ^ 2 - 6 L

and click option =
