Triangle DEF has sides of length 10 units, 24 units, and 26 units. Determine the area of triangle DEF.
To find the area of a triangle, you can use Heron's formula, which states that if the lengths of the sides are $a$, $b$, and $c$, and $s = \f\frac{a + b + c}{2}$ (the semi-perimeter), then the area $A$ is given by:
$A = \sqrt{s(s-a)(s-b)(s-c)}$.
