The area of a triangle is a measurement of the region enclosed by the three sides of a triangle. The formula for calculating the area of a triangle is 1/2 base x height, where the base is the length of one side of the triangle and the height is the perpendicular distance from that side to the opposite vertex.

The area of a triangle is widely used in geometry and trigonometry, as well as in various applications such as architecture, engineering, and physics. For example, architects use the area of triangles to calculate the amount of material needed for roofing or flooring, while engineers use it to design structures such as bridges and towers.

In everyday life, we also encounter triangles in various shapes and sizes, from the triangular shape of a slice of pizza to the triangular sails of a sailboat. By calculating the area of a triangle, we can better understand and appreciate the mathematical principles that underlie these everyday objects and phenomena.

The formula for determining the area of a triangle is defined as:

\(A\) \(=\) \(\dfrac{h \cdot b}{2}\)

\(A\): the area of the triangle

\(h\): the height of the triangle

\(b\): the length of the base

The SI unit of area is: \(square \text{ } meter\text{ }(m^2)\)
