x, x+2, x+4 are the 3 sides.
x+x+2+x+4=105
3x+6=105
3x=99
x=a=33, b=35 c=37
s=(a+b+c)/2
s=(33+35+37)/2
s=105/2=52.5
Heron's area formula: A=sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29
A=sqrt%2852.5%2852.5-33%29%2852.5-35%29%2852.5-37%29%29
A=sqrt%2852.5%2819.5%29%2817.5%29%2815.5%29%29
A=sqrt(277692)
A=562.965
