ΔDEF is similar to ΔGHI. Length of DE is 16 cm and length of the corresponding side GH is 25 cm. What is the ratio of areas of ΔDEF : ΔGHI?
It is given that ΔDEF $$\sim$$ ΔGHI
Also, length of DE = 16 cm and length of the corresponding side GH = 25 cm
=> Ratio of Area of ΔDEF : Area of ΔGHI = Ratio of square of corresponding sides = $$(DE)^2$$ : $$(GH)^2$$
= $$\frac{(16)^2}{(25)^2} = \frac{256}{625}$$
$$\therefore$$ The required ratio is 256 : 625
=> Ans - (C)
