Sagot :

Answer:

480 cm²

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
