If DeltaABC~DeltaDEF , AB=4cm, DE=6, EF=9 cm and FD=12 cm, then find the perimeter of DeltaABC .

If DeltaABC~DeltaDEF , AB=4cm, DE=6,EF=9 cm and FD=12 cm, then find the perimeter of DeltaABC .

If DeltaABC ~ DeltaDEF AB =4 cm , DE = 6 cm, EF =9 cm and FD =12 cm find the perimeter of DeltaABC .

∆ABC ~ ∆DEF. If AB = 4 cm, BC = 3.5 cm, CA = 2.5 cm and DF = 7.5 cm, find the perimeter of ∆DEF

If Delta ABC-Delta DEF,BC=3cm,EF=4cm and area of Delta ABC=54sqcm then find the area of Delta DEF

In the right-angled triangle ABC , /_B=90^(@) and the points D and E are on the sides AC and BC such that DE||AB . If AB=9cm , DE=3cm and AC=24cm , then find the value of AD .

In Delta ABC , M and N are the midpoints of AB and AC respectively. If AB = 8 cm, AC = 7 cm and MN = 4.5 cm, find the perimeter of Delta ABC .

If ABCDEF such that AB=9.1cm and DE=6.5cm. If the perimeter of DEF is 25cm, then the perimeter of ABC is (a) 36cm (b) 30cm(c)34cm(d)35cm

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

Given two triangles ABC and DEF. If Delta ABC ~ Delta DEF, 2AB = DE and BC = 8 cm, then find the length of EF.
