These dimensions would not not form a triangle.

Explanation:

For a triangle to be formed, the sum of two sides should be greater than the third side.
suppose, a=4; b=8; c=12

It can be seen, a+b = c (and not greater than c), so the triangle cannot be formed.

In case, there is corrected length, then one can use Heron's formula:
A = #sqrt (s(s-a)(s-b)(s-c)#
where, #s = (a+b+c)/2#
