Question

1) The ratio of corresponding sides of similar triangles is 5:2,then find the ratio of their areas​

Answer 1

Answer:

please refer to the attachment

Answer 2

Answer:

The ratios of their areas is 25:4.

Step-by-step explanation:

Given data :

The ratio of corresponding sides of similar triangles is 5:2.

Formula to be used :

The ratio of the areas of two similar triangles is equal to the ratio of square of their corresponding sides

If ABC and DEF are similar triangles, then :

$\frac{ar(ABC) }{ar( DEF)} = \frac{ {AB}^{2} }{ \ {DE}^{2} }$

Calculations :

The ratios of their areas will be :

$\frac{ {5}^{2} }{ {2}^{2} } = \frac{25}{4}$

Hence, the required ratio is 25:4.
