Question

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the triangle. a = 240 b = 127 c = 281 No triangle is formed. 21,237.83 21,223.73 15,183.77

Answer 1

If a,b,c are the sides of a triangle,then
a+b>c,where a,b and c are any two sides or sum of any two sides is greater than third.
2s=a+b+c
\[area=\sqrt{s \left( s-a \right)\left( s-b \right)\left( s-c \right)}\]
