Area of a triangle is the region covered by its three sides in a plane. Area of a triangle is equal to half of product of its base and height. Find the area using heron's formulas and SAS condition, with examples at BYJU'S.
The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h. This formula is applicable to all types of triangles, whether it is a scalene triangle, an isosceles triangle, or an equilateral triangle.
Apr 13, 2024 · To calculate the area of a triangle, start by measuring 1 side of the triangle to get the triangle's base. Then, measure the height of the triangle by measuring from the center of the base to the point directly across from it.

3 days ago · Triangle area formula. A triangle is one of the most basic shapes in geometry. The best known and the most straightforward formula, which almost everybody remembers from school, is: area = 0.5 × b × h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
The area of the rectangle is b h = 4 × 5 = 20 square units, so the area of the triangle is 1 2 b h = 1 2 × 4 × 5 = 10 square units. Key intuition: A triangle is half as big as the rectangle that surrounds it, which is why the area of a triangle is one-half base times height.
The formula most commonly used to find the area of a triangle is –. A = \frac {1} {2} \cdot \text {base} \cdot \text {height} A = 21 ⋅base ⋅height. We can take any side of the triangle as the base. The corresponding height would be the perpendicular drawn to the base from the opposite vertex. Here, AD is the height corresponding to the base BC.
Area of a Triangle tutorial. Pictures, examples and many practice problems on how to find the area of a triangle from its base and its height.
Area of a Triangle Formula. The area of a triangle [latex]A[/latex] is half the product of its base [latex]b[/latex] and its height [latex]h[/latex]. The height of a triangle is also known as the altitude. This formula works only if the base is perpendicular to the height.
If we are given the lengths of two sides of a triangle and the size of angle between them we can use the formula: \(Area = \frac{1}{2}ab\sin C\) The area of a triangle is equal to half the product of two sides times the sine of the included angle. This is also known as the sine rule for the area of a triangle.
The formula for the area of a parallelogram is base × height, written as Area = b × h. A diagonal of a parallelogram divides it into two congruent triangles as shown in parallelogram ABCD below. Since ABC≅ CBD, the area of ABC is half the area of the parallelogram.
