Answer 2

The required ratio would be 36:49.

Step-by-step explanation:

Since we have given that

Δ ABC is similar to ΔDFE.

As we have

AB = 1.2 cm

DE = 1.4 cm

So, According to "Area Similarity theorem", we get that

$\dfrac{ar(ABC)}{ar(DFE)}=\dfrac{AB^2}{DE^2}=\dfrac{1.2^2}{1.4^2}=\dfrac{1.44}{1.96}=\dfrac{0.36}{0.49}$

Hence, the required ratio would be 36:49.
