The sides of a triangle are 5:8:10 and it's perimeter is 23 cm. find the area of triangle.

19.81cm^2

Step-by-step explanation:

To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:

sqrt(p*(p-a)*(p-b)*(p-c))

Plugging the values into this formula gives 19.81cm^2.
