The equation for the length is L=2W - 3. The perimeter is 48 cm and the equation for finding the perimeter is P = 2W + 2L. Substitute the formula of L into the formula for perimeter and solve algebraically:

$P = 2W +2L \\ 48= 2W + 2(2W-3) \\ 48=2W + 4W - 6 \\ 48 = 6W - 6 \\ 48+6 = 6W \\ 54=6W \\ W=9 \\ L=2(9)-3 = 15$

The correct answer is A) length = 15cm; width = 9cm
