Use an appropriate area formula to find the area of the tria
     Use an appropriate area formula to find the area of the triangle with the given side lengths.  a = 16 m  b = 7 m  c = 10 m  What is the area of the triangle?  m^2 (Round your answer to the nearest tenth) 
  
  Solution
Area of the triangle with 3 sides given can be calculated using heron\'s formula -
A = (s (s-a) (s-b)(s-c))0.5
s = (a+b+c)/2
s = (16+7+10)/2 = 33/2 = 16.5
A = (16.5 (16.5-16) (16.5-7)(16.5-10))0.5
A = 22.57 m2
