Question

Triangle JKL is similar to triangle MNO.What is the perimeter of triangle MNO?

Answer 1

20

Explanation:

Answer 2

Answer: The perimeter of triangle MNO is 20.

Step-by-step explanation:

1. Find the scale factor between the two triangles by dividing 6 by 9 (yellow side), or 4 by 6 (pink side). Either way, you get the result 2/3. So 2/3 is the scale factor.
2. Multiply 15 (green side of triangle JKL) by the established scale factor to get 10, which is equal to x.
3. Add 4, 6, and 10 together to get 20. This is the perimeter of MNO, as you find the perimeter of a triangle by adding the lengths of all of its sides together.
