Answer
The area of a triangle can be found using Heron’s formula. Heron’s formula is a mathematical formula used to calculate the area of a triangle when the lengths of all three sides are known.
Detailed Explanation
Heron’s formula is a mathematical formula used to calculate the area of a triangle when the lengths of all three sides are known. The formula is derived from the Pythagorean Theorem and states that the area of a triangle is equal to the square root of s(s – a)(s – b)(s – c), where s is half of the perimeter of the triangle and a, b, and c are the lengths of the sides of the triangle.
To calculate the area of the triangle given by Rachel, the lengths of all three sides must be known. Once these lengths are known, half of the perimeter of the triangle (s) can be calculated by adding the lengths of all three sides and dividing by two. Then, the area of the triangle can be calculated using Heron’s formula by substituting the values of s, a, b, and c into the formula.
