Answer: 540 cm²
Step-by-step explanation:To find the area of the dilated rectangle, we need to first find the dimensions of the new rectangle after it has been dilated by a factor of 3.
The length of the new rectangle will be 3 times the original length, which is:
10 cm x 3 = 30 cm
The width of the new rectangle will also be 3 times the original width, which is:
6 cm x 3 = 18 cm
Therefore, the area of the dilated rectangle will be:
30 cm x 18 cm = 540 cm²
