Question

let triangle ABC ~ triangle DEF and their areas be resoectively, 64 cm sq and 121 cm sq. If EF=15cm, 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. Weknow 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.
