Explanation
The area of a triangle is given by the product between its base and its height divided by two. Any of the three sides of the triangle can be selected as the base and its height will depend on this selection. The height of the triangle is equal to the perpendicular distance between the base and its opposite vertex.
As you can see in the picture if we choose the 8 cm long side to be the base then the height of the triangle would be h i.e. 6.2172 cm. Then its area is:
[tex]A=\frac{1}{2}bh=\frac{1}{2}\cdot8\text{ cm}\cdot6.2172\text{ cm}=49.7376\text{ cm}^2[/tex]Answer
Then the answer is 49.7376.
