Find the area of a triangle with a =4, b =6, and c =8.
Accepted Solution
A:
Answer:DStep-by-step explanation:The area of the triangle can be calculated using formula[tex]A=\sqrt{p(p-a)(p-b)(p-c)},[/tex]where p is half of the perimeter.1. If a=4, b=6 and c=8, then[tex]p=\dfrac{a+b+c}{2}=\dfrac{4+6+8}{2}=9\ un.[/tex]2. The area is[tex]A=\sqrt{9\cdot (9-4)(9-6)(9-8)}=\sqrt{9\cdot 5\cdot 3\cdot 1}=3\sqrt{15}\approx 11.6\ un^2.[/tex]
