Math Problem Statement
Solution
To calculate the area of the triangle, we can use Heron's formula since we know the lengths of all three sides of the triangle. The sides of the triangle are given as:
Step 1: Calculate the semi-perimeter ():
The semi-perimeter is half of the triangle's perimeter, calculated as:
Step 2: Apply Heron's formula:
Heron's formula for the area of a triangle is:
Substitute the values of , , , and :
I'll now calculate the exact area.The area of the triangle is approximately 27.81 cm².
