A) \[9:4\]
B) \[3:2\]
C) \[4:9\]
D) \[2:3\]
Correct Answer: A
Solution :
We know that, the ratio of the areas of similar triangles is equal to the ratio of the squares of the corresponding sides. |
Therefore, |
\[\frac{ar(\Delta ABC)}{ar(\Delta DEF)}\,\,=\frac{A{{B}^{2}}}{D{{E}^{2}}}=\frac{{{15}^{2}}}{{{10}^{2}}}=\frac{225}{100}=\frac{9}{4}\] |
So. option [a] is correct. |
