If two triangles are similar and the ratio of their corresponding altitudes is 3:7, find the ratio of their areas.

Question

Accepted Answer

1. For similar triangles, all linear measures scale the same. The altitudes ratio is $3:7$.
2. Area scales as the square of a linear ratio.
3. So the area ratio is $3^2:7^2 = 9:49$.
4. Therefore the correct choice is **(b) 9:49**.
