Answer 1

HEY MATE!!!

Here's the answer with explanation...    

In two similar triangles, the sides, altitudes and medians are in the same ratio. If the ratio is a:b, then the ratio of their areas will be a²:b².

Here,

⇒ A(ΔABC) : A(ΔDEF) = 121:64

⇒ a²:b² = 121:64

⇒ a:b = √121:√64

⇒ a:b=11:8

So the sides, altitudes and medians are in the ratio 11:8!!!

⇒ AM : DN = 11:8

⇒ 12.1 : DN = 11:8

⇒ 12.1/DN = 11/8

⇒ DN = 12.1 / (11/8)

⇒ DN = 12.1 / 11 × 8

⇒ DN = 8.8

So the median of ΔDEF is 8.8 cm!!!

Thank you...
