Find the length of perpendicular from the opposite vertex to the side whose length is 12 cm LONG ANSWER TYPE QUESTIONS Q 9 The lengths of two adjacent sides 

  • How do you solve the Heron formula question?

    Step 1: Find the perimeter of the given triangle.
    Step 2: Find the semi-perimeter by halving the perimeter.
    Step 3: Find the area of the triangle using Heron's formula √(s(s - a)(s - b)(s - c)).
    Step 4: Once the value is determined, write the unit at the end (For example, m2, cm2, or in2).

  • Is Heron a trigonometry formula?

    is the semiperimeter of the triangle: s = a + b + c 2 {\\displaystyle s={\\frac {a+b+c}{2}}} There is a proof here.

  • Heron's formula, formula credited to Heron of Alexandria (c. 62 ce) for finding the area of a triangle in terms of the lengths of its sides.
    In symbols, if a, b, and c are the lengths of the sides: Area = Square root of√s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + c)/2.
