Question

The perimeter 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

Answer: 5.4 cm

Step-by-step explanation:

let the required side be x

ratio of perimeter of 2 triangles = ratio of 2 corresponding sides of triangles

=> 25/15 = 9/x

=> 5/3 = 9/x

=> x = 27/5

= 5.4 cm

Answer 2

Step-by-step explanation:

perimeter of triangle first / perimeter of triangle second = one side /second side

25/15 = 9/x

15 × 9 = 25 x

135 = 25 x

135/25 = x

5.4 = x

therefore the corresponding side of second triangle is 5.4 cm
