Answer: Thus, the perimeter is 36 cm.Example 3: The length of the sides of a triangle ABC are 7 units, 9 units, and 12 units. Calculate its area.Solution:Given:Sides of the triangleLet a = 7 units, b = 9 units, c = 12 units .Using Heron's Formula: Area of triangle = √(s...
Other methods to calculate a triangle's area include using the lengths of two sides and the angle between them (A = a × b × sin(γ) / 2), two angles and the side between them, or the lengths of all three sides with Heron's formula. It's inevitable. At some point in every ma...

2. Area of triangle is also calculated using Heron’s formula Conclusion So far, we have learned that area is the two-dimensional space any object takes. Learning about shapes and their area and perimeter becomes much more interesting when we understand them with real-life applications. The use...

We can then proceed to use the heron's formula on the middle triangle EPD and get the area of EPD as 32, (its simple computation really, nothing large). Then we can find the areas of the remaining triangles based on side and ratio length of the bases....

When we don’t have the base and height for the scalene triangle and we have given the sides, then we apply Heron’s formula.Area of the triangle $= \sqrt{s(s-a)(s-b)(s-c)}$ square unitsWhere, s is the semi perimeter of a triangle, therefore, $\text{s}=\frac{a+b+c}{2...
