Question

Abc def and area of abc 121cm and other 64 cm medianof abc is 12.1 what is the median of def

Answer 1

Answer:

Given,

AREA(ABC) =121 cm cubed

AREA(DEF) = 64 cm cubed.

We know that by area theorem ,

Ar(ABC)/Ar(DEF) = (median of ABC/Median DEF)²

=>121/64 = (12.1/Median of DEF)²

=>11/8 = 12.1 / Median DEF             --------------(After square rooting both sides)

=>Median DEF = 12.1 x 8 / 11

=>Median DEF = 8.8 cm

Hope this helps.
