Question

the perimeter of two similar triangles triangle ABC and triangle pqr are 35 cm and 45 CM respectively the ratio of area of two triangle is​

Answer 1

Answer:

Ratio of parameter and sides will be same .

So ratio of sides of similar triangle

$r = \frac{35}{45} = \frac{7}{9}$

So ratio of area

$= {r}^{2} = ( \frac{7}{9} ) {}^{2} = \frac{49}{81}$
