In triangle `DEF, DE=DF=10 and EF=16`. What is the area of the triangle?

triangle DEF~triangle MNK , if DE=5 and MN=6, then find the value of A(triangle DEF):A(triangle MNK) .

If triangle ABC ~ triangle DEF if DE : AB = 2 : 3 and area of triangle DEF = 44 sq.units then find the area of triangle ABC .

In triangle ABC , AB=AC and AL is perpendicular to BC at L. In triangle DEF , DE=DF and DM is perpendicular to EF at M. If (area of triangle ABC ):(area of triangle DEF )= 9:25 then (DM+AL)/(DM- AL) is equal to: त्रिभुज ABC में, AB = AC है तथा AL, BC पर L पर डाला गया लम्ब है| triangle DEF में, DE = DF है तथा DM, EF पर M पर डाला गया लम्ब है| यदि ( triangle ABC का क्षेत्रफल ): ( triangle DEF का क्षेत्रफल )= 9 : 25 है, तो (DM+AL)/(DM- AL) का मान किसके बराबर है ?

triangle ABC ~ triangle DEF , BC = 5 cm, EF = 6cm and area of triangle DEF = 72 cm^2 . Determine the area of triangle ABC

Statement - I : Let the side DE of a triangle DEF be divided at S so that (DS)/(DE)=(1)/sqrt(2) . If a line through S parallel to EF meets DF at T, then the area of triangle DEF is twice the area of the triangle DST. Statement - II : The areas of the similar triangles are proportional to the squares on the corresponding sides. Which one of the following is correct in respect of the above statements ?

If triangle ABC~triangle DEF such that the area of triangle ABC is 9 cm^2 and the area of triangle DEF is 16 cm^2 . If BC=2.1 cm, find the length of EF.

The area of triangle DEF is 32sqrt(3) square units. What is the length of overline(DF) ?
