Question

A triangle drawn on a map has sides that measure 15 cm, 8 cm, and 10 cm. The shortest of the corresponding real-life distances is 127 km. Find the longest of the real-life distances.

Answer 1

Set up a proportion.

8/127=15/x

Cross multiply

8x=1,905

Divide both sides by 8

x=238.125

The longest of the real-life distances is 238.125 km.

Hope this helps :)
