Answer:
Hello!
Your answer is most likely to be 325m...
Step-by-step explanation:
Looking at the map you'll mostly need and good inference skills to answer the question...
The closest line is 300m right?
So if T is like in the middle (halfway because it doesn't form another line (i.e. it +25m), it means it is at a HIGHER elevation than at the last measurement...it could even be the PEAK!
So it would be 325m because :
1. The different topographic lines go up only in 50's: T is halfway along this because it doesn't really form a new line...
2. It is in the middle of a circle at 300m...this means that it WONT be any lower than 300m (or insanely higher like 450!)
I HOPE THIS HELPED!
