Answer:

480 cm²

Step-by-step explanation:

New side lengths:

80% of 30 cm = 0.8% × 30 cm = 24 cm

80% of 25 cm = 0.8 × 25 cm = 20 cm

area = length × width

area = 24 cm × 20 cm

area = 480 cm²

Answer:

480 cm^2

Step-by-step explanation:

20% of 30 = 6   30 - 6 = 24

20% of 25 = 5   25 - 5 = 20

area = length * width

20 * 24 = 480 cm^2
