The ratio of the area if triangle ABC to triangle A'B'C is 49/4. What is the scale factor used to dilate triangle ABC to form triangle A'B'C? a) 49/4
b) (49/4) ^2
c) 12.25
d) 2/7
please help :/

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
