Question

Two triangles are similar. The lengths of the sides of the smaller triangle are 5,6,and 9. The perimeter of the larger triangle is 50. What are the lengths of the sides of the larger triangle?

Answer 1

Let the sides of the larger be 5x, 6x, and 9x
5x+6x+9x = 60

solve for x, sub x into the definitions.

Answer 2

obviously the lengths are 23.5, and 27.
