The area of the given triangle will be equal to 35cm.
What is an area?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.
Given that:-
sides(s)=10,8,9
Semi perimeter(p) = a + b + c / 2
= 10 + 9 + 8 / 2
= 13.5
The area of a triangle(a) will be calculated as:-
[tex]A =\sqrt {s(s-a)(s-b)(s-c)[/tex]
[tex]A= \sqrt{13.5[(13.5-9)(13.5-8)(13.5-10)[/tex]
A = 34.19
Therefore the area of the given triangle will be equal to 35cm.
