To get from your house to your grandparent’s house you must avoid walking through a pond. to avoid the pond, you walk 5 meters south and 12 meters east. how many meters would be saved if it were possible to walk through the pond?

The meters that would be saved is 17 meters

You would use the Pythagorean theorem. 

a^2+b^2=c^2 

so 

5^2+12^2=c^2 

25+144=169 

square root of 169 is 13. 

originally you walked 17 meters. 

17 minus 13 is 4. 

you save 4 meters if you were able to go straight.
