Question

Triangles ABC and DEF are similar If AB = 1.2 cm and DE = 1.4 cm, find the ratio of the areas of ΔABC and ΔDEF.

Answer 1

We have,

ΔABC ~ ΔDEF

AB = 1.2 cm and DF = 1.4 cm

By area of similar triangle theorem

`("Area"(triangleABC))/(Area(triangleDEF))="AB"^2/"DE"^2`

`=1.2^2/1.4^2`

`=1.44/1.96`

`=36/49`
