Apologies for the mistake. Let's recalculate:
Original width: 10 cm
Original height: 4 cm
A. New width after a scale factor of 3: 30 cm [(10 cm) * 3 = 30 cm] - Correct
B. New length after a scale factor of 4: 16 cm [(4 cm) * 4 = 16 cm] - Correct
C. New perimeter after a scale factor of 2: 56 cm [2*(10+4) = 28 cm + 28 cm = 56 cm] - Correct
D. New area after a scale factor of 2: 160 cm² [(10*4)*2 = 80 cm²] - Incorrect
Therefore, the correct statements are A, B, and C. Thank you for pointing out the error.
