Answer 1

$\huge\red{\underline{❥Solution}}$

We know that the ratio of areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.

$area \: (def) = de {}^{2} \div area \: (abc) = ab {}^{2}$

⇒ Area(△DEF) ÷ Area(△ABC)

⇒ (1.2)² ÷ (1.2)²=(12/14)²

⇒ 36 ÷ 49

Answer 2

We know that the ratio of areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.

area \: (def) = de {}^{2} \div area \: (abc) = ab {}^{2}area(def)=de

2

÷area(abc)=ab

2

⇒ Area(△DEF) ÷ Area(△ABC)

⇒ (1.2)² ÷ (1.2)²=(12/14)²

⇒ 36 ÷ 49

here is your answer
