Question

. The perimeters of two similar triangles are 25cm and 15cm. If one side of the first triangle is 9cm, find
the corresponding side of the second triangle.​

Answer 1

9:25 = x:15

x= 135/25= 5.4

as the triangles are the same but just dilated, the ratio of the side to the total perimeter will be same for both the triangles. Therefore, 9:25 will be same as x:15 where x is the corresponding triangle.

Answer 2

Answer:

DE = 5.4cm

Step-by-step explanation:

∆ABC~∆DEF

(∆)  / (∆)

=  (++)  / (++ ) =   /

=>    25 /15  =  9 /

=>    X = 5.4cm

=>    DE = 5.4cm
