[QUOTE=Syeda Bukhari;620562]How 240? Please help me understand so I may not make that mistake in future.

As far as my knowledge works, it's 180m.

120m is the length of the river.
Quarter from left means 1/4x120=30
Quarter from right means 1/4x120=30
So: 120+30+30=180

Do let me know if Iam wrong.

Stay blesses
