If the length of three sides of a triangle is given, then we use Heron’s formula to calculate the area of the triangle. Area of triangle = √[s(s – a)(s – b)(s – c)], where s is the semi-perimeter of the triangle, and a, b, c are lengths of the three sides of the triangle.

Whether you have the base and height of the triangle, three sides, side-angle-side, or angle-side-angle, this versatile triangle area calculator will find the area of a triangle for you.
Area of Triangle with Three Sides (Heron’s Formula) The area of a triangle with 3 sides of different measures can be calculated using Heron’s formula. Heron’s formula includes two important steps. The first step is to find the semi perimeter of a triangle by adding all three sides of a triangle and dividing it by 2.
30 Ιουλ 2024 · The 3 sides triangle area calculator is here to the rescue if you need to calculate the area of a triangle but only know the three side lengths. A good example is trying to figure out the area of a triangular-shaped room – with this calculator, you'll learn how to find the square footage of a triangle room.
19 Μαΐ 2020 · I have used the sine rule (or law of sines) to find one of the sides and used the formula area $=\frac{1}{2}ac\sin B$. I used a calculator here, but you could easily calculate $\sin 15$ using the compound angle formulae if this was from some competition.
What is the Area of a Triangle with Sides 3, 5, 7? If the three sides of a triangle are given as 3, 5 and 7, its area can be calculated with the formula, area = √[s(s-a)(s-b)(s-c)]. In this case, a = 3, b = 5, c = 7, and s (semi perimeter) = 7.5.
How to Find the Area of a Triangle with 3 Sides? The area of a triangle with 3 sides can be calculated using Heron's formula. Heron's formula: A = \(\sqrt {s(s - a)(s - b)(s - c)}\) where a, b, and c are the sides of the triangle and 's' is the semi-perimeter; s = (a + b + c)/2.
