if the parameters of two similar triangles ABC and d e f are 50 cm and 70 cm respectively and one side of triangle ABC = 20 CM then find the corresponding side of triangle d e f

We have,ABC~DEF   givenPerimeter of ABC = 50 cmPerimeter of DEF = 70 cmLet AB = 20 cm; DE = ?We know that ratio of perimeters of 2 similar 's is equal to the ratio of their corresponding sides.Now, Perimeter of ABCPerimeter of DEF = ABDE = BCEF = ACDFPerimeter of ABCPerimeter of DEF = ABDE5070 = 20DEDE = 140050 = 28 cm
