Question

If triangle ABC is congruent to triangle DEF and their Areas are respectively 64cm2 and 121cm2.if EF =15.4cm then find BC

Answer 1

Step-by-step explanation:

Let ∆ABC ~ ∆DEF and their areas be, respectively, 64 cm2 and 121 cm2. If EF = 15.4 cm, find BC. We know that the ratio of areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides. Hence, BC = 11.2 cm.
