I don't have a visual I can provide, but the ratio of the areas is the square of the ratio of the perimeters of a 2D figure.
Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.
Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.
Option D:
The solution to the equation is y = 27.
Solution:
Given equation:

To solve this equation:

Multiply by 3 on both sides of the equation.

3 in the numerator and denominator get canceled.
y = 9 × 3
y = 27
The solution to the equation is y = 27.
Option D is the correct answer.
