Question 83

ΔABC is similar to ΔDEF. Length of AB is 12 cm and length of the corresponding side DE is 8 cm. What is the ratio of Perimeter of ΔABC : Perimeter of ΔDEF?

Solution

It is given that ΔABC $$\sim$$ ΔDEF

Also, length of AB = 12 cm and length of the corresponding side DE = 8 cm

=> Ratio of Perimeter of ΔABC : Perimeter of ΔDEF = Ratio of corresponding sides = AB : DE

= $$\frac{12}{8} = \frac{3}{2}$$

$$\therefore$$ The required ratio is 3 : 2

=> Ans - (C)
