Keep your teacher "happy":
A = Area, L = Length, W = Width
2L + 3W = 480 [1]
A = LW [2]
[1]: 2L = 480 - 3W
L = (480 - 3W) / 2
Substitute in [2]:
A = W(480 - 3W) / 2
2A = W(480 - 3W)
continue...
Where in the problem statement - this relationship is indicated?
The problem does not say the rectangles are congruent!
