Answer
$1.73 \ square \ units $
Work Step by Step
According to Heron's formula, the area of a triangle with sides $a,b$ and $c$ is given by:
$K=\sqrt{s(s-a)(s-b)(s-c)}$; where $s=\dfrac{a+b+c}{2}$
Therefore, $s=\dfrac{2+2+2}{2}=3$
In order to find the area of a triangle we will have to substitute the data into Heron's formula.
$K=\sqrt{3(3-2)(3-2)(3-2)} \approx 1.73 \ square \ units $
