ΔABC ~ ΔDEF, AB=9.1 cm and DE=6.5 cm, if the perimeter of ΔDEF=25 cm, what is the perimeter of ΔABC in cm?

- 35
- 28
- 42
- 40

**Answer: (1) 35 **

**Solution:-**

AB = 9.1 cm and DE = 6.5 cm

Then the ratio of Side AB and DE = 9.1/6.5

= 7: 5

The perimeter of triangle DEF = 25 cm

Then the perimeter of triangle ABC = 25 x 7/5

= 5 x 7

= 35 cm

Hence, the correct answer is option (1) 35.
