Answer 2

Answer: 640

Explanation:

Since the two triangles are similar we can simply multiply the lesser triangle's area by a constant to get our answer.

Polygon FGHIJ is ABCDE with a scale change of 4

For the reason that we are dealing with area, we will multiply 40 by 4² in stead of just 4.

40 * 16 = 640
