What percentage of the body is burned if a 16 year old male burned his back, the back of his left leg, and his entire right arm?

You can solve this question using "rule of nine" to calculate the area of the body. Each arm equals to 4.5% so entire arms would be 4.5%.
Each side of body trunk equal to 18%, so entire back would be 18%.
Each leg equal to 18%, back of the leg would be half of it so it will be 9%.
The total would be: 4.5%+ 18%+9%= 31.5%

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
