The area of the triangle is approximately 1533.01 cm².
Solution
To find the area of a triangle when all three sides are known, we can use Heron’s formula.
Heron’s formula states that the area of a triangle with sides of length
,
, and
is given by:
where
is the semi-perimeter of the triangle, calculated as:
Given the sides of the triangle are
, and
, we can calculate the semi-perimeter and then use Heron’s formula to find the area of the triangle.
