Question

perimeters of two smiliar triangles are 30 and 20 cms . if one side of first triangle is 12 cm find corresponding side of another triangle?​

Answer 1

Answer:8 cm

Step-by-step explanation:

Let the missing side be of 'x' cm

We know that the ratio of the perimeter of similar triangles is equal to the ratio of the corresponding sides of the triangles

Thus, 30/20=12/x

3/2=12/x

(2)(12) = (3)(x)

24 = 3x

X = 24/3 = 8 cm
