Answer: 33 square units

Explanation:

Given: Sides lengths of the triangle : 16 units, 10 units, 8 units.

Heron's formula:-


\text{Area of triangle}=√(s(s-a)(s-b)(s-c)), where s is the semiperter and a,b and c are the side-lengths of the triangle.

Let a=16 , b=10 and c=8

Then,


s=(a+b+c)/(2)=(16+10+8)/(2)=17

Using Heron's formula:-


\text{Area of triangle}=√(17(17-16)(17-10)(17-8))\\\\\Rightarrow\ \text{Area of triangle}=√(1071)=32.7261363439\approx33\text{ square units}
