Question

Triangle ABC similar triangle DEF with AB=BC=3cm,AC =4cm,DE=2fm then EF and DF are respectively

Answer 1

Answer:

Since the ratio of areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.

∴ Area(△DEF)Area(△ABC)=EF2BC2

⇒ Area(△DEF)54=4232

⇒ Area(△DEF)=954×16=96cm2
