`triangle ABC ~ triangle DEF` such that DE =3 cm, EF = 2 cm, DF = 2.5 cm and BC = 4 cm, find the perimeter of `triangle ABC`

triangle ABC - triangle DEF such that DE = 3 cm, EF = 2 cm, DF = 2.5 cm " and " BC = 4 cm. Find perimeter of triangle ABC .

DeltaABC ~ Delta DEF such that DE = 3 cm , EF = 2 cm , DF = 2.5 and BC = 4 cm . Find the perimeter of DeltaABC.

DeltaABC~DeltaDEF such that DE=3cm,EF=2cm,DF=2.5cm and BC=4cm . Find the perimeter of DeltaABC.

In the given fig. AP = 4 cm, BQ = 6 cm and AC = 9 cm. Find the semi perimeter of Delta ABC .

If ABC and DEF are similar triangles such that AB=3cm,BC=2cmCA=2.5cm and EF=4cm, write the perimeter of DEF

triangle ABC ~ triangle EDF and ar(triangle ABC) : ar(triangle DEF) = 4 : 9 . If AB = 6 cm, BC = 8 cm and AC = 10 cm, then DF is equal to : triangle ABC ~ triangle EDF और ar(triangle ABC) : ar(triangle DEF) = 4 : 9 है। यदि AB = 6 सेमी, BC = 8 सेमी तथा AC = 10 सेमी है, तो DF का मान क्या होगा ?

In triangle ABC and triangle DEF, AB = DE, BC = EF and angleB = angleE . If the perimeter of triangle ABC is 20, then the perimeter of triangle DEF is ..........

triangle ABC ~ triangle EDF and ar(triangle ABC) : ar(triangle DEF) = 1:4 . If AB =7cm, BC = 8 cm and CA = 9 cm, then DF is equal to : triangle ABC ~ triangle EDF और ar (triangle ABC) : ar(triangle DEF) = 1: 4 है। यदि AB = 7 सेमी, BC = 8 सेमी तथा CA = 9 सेमी है, तो DF का मान किसके बराबर होगा?

If triangle ABC is similar to triangle DEF such that 2AB = DE and BC = 8 cm then EF is .

In figure , DE "||"BC in triangle ABC such that BC = 8 cm , AB = 6 cm and DA = 1.5 cm .find DE.
