A gas pipeline must be diverted around a swamp as shown below. The pipeline costs $1225/m to install. How much more money would have to be spent to divert the pipeline around the swamp?
Here is an image to help.
Keep in mind, I am only in grade 11 math, please keep things simple.
Your teacher is claiming that the added distance is $1.27$ km, which means the straight line distance is $5.28$ km. There is not enough information in the problem to make that claim. I tried making the angle right, but that doesn't work. The added distance is larger than that.
