Question 94

Δ ABC and Δ DEF are similar triangles. Length of AB is 10 cm and length of the corresponding side DE is 6 cm. What is the ratio of Perimeter of ΔABC to ΔDEF?

Solution

It is given that ΔAB $$\sim$$ ΔDEF

Also, length of AB = 10 cm and length of the corresponding side DE = 6 cm

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

= $$\frac{10}{6} = \frac{5}{3}$$

$$\therefore$$ The required ratio is 5 : 3

=> Ans - (A)
