Answer:
480 cm²
Step-by-step explanation:
If we scale the figure by a factor of k, the area of the figure will be increased by a factor of k².
Then, if the base and height are scaled by a factor of 4 the area of the resulting triangle will be equal to:
Final Area = 4² x (Initial Area)
Final Area = 16 x 30 cm²
Final Area = 480 cm²
Therefore, the area of the resulting triangle will be 480 cm²
