प्रश्न
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.
उत्तर
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`
