Question

Let ⚠ABC is similar triangle to DEF and there areas be respectively 64 and121 if EF =15.9 find BC​

Answer 1

Step-by-step explanation:

It is given that:

∆ABC ~ ∆DEF

We know that the ratio of areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.

see the attachment given above

Hence, BC = 11.2 cm.
