[0010001111]... Hello User... [1001010101]
Here's your answer...

$a = 3 \\ b = 4 \\ c = 5 \\ s = \frac{a + b + c}{2} \\ = \frac{3 + 4 + 5}{2} = 6$

$A = \sqrt{s(s - a)(s - b)(s - c)} \\ = \sqrt{6 \times (6 - 3) \times (6 - 4) \times (6 - 5) } \\ = \sqrt{6 \times 3 \times 2 \times 1 } \\ = \sqrt{6 \times 6} \\ = 6$
The area of the triangle is 6 sq. units
