Question

Use a proportion to solve the problem. Round to the nearest tenth as needed. A triangle drawn on a map has sides of lengths 9 cm, 11 cm, and 13 cm. The shortest of the corresponding real-life distances is 106 km. Find the longest of the real-life distances.

Answer 1

I get x/13 = 106/9............so 9x = 1378 therefore x = 153.1
