D. 6A
When the base is doubled and the height is tripled, the area of the new triangle will be 6 times the area of the original triangle. This is because area is calculated as (base * height) / 2, and when the base is doubled and the height is tripled, the new area will be (2 * 3 * A) / 2 = 6A.
Let A be the area of a triangle. If the
lengths of the base and height are doubled
and tripled, respectively, what is the area
of a new triangle in terms of A?
A. A
B. 2A
C. 3A
D. 6A
E. 12A
