Select a type of triangle below
The perimeter of an acute triangle is the sum of the lengths of its three sides. An acute triangle is a type of triangle where all three angles measure less than 90 degrees. Acute triangles are common in geometry and can be found in many real-life situations, such as in construction, architecture, and engineering.
For example, the roof of a house may be in the shape of an acute triangle, and its perimeter would be the sum of the lengths of the three sides. Similarly, the shape of a wedge used in carpentry or woodworking may also be an acute triangle, and its perimeter would be calculated in the same way. In the field of trigonometry, the perimeter of an acute triangle is used in various calculations, such as finding the lengths of its sides or angles.
The formula for determining the perimeter of an acute triangle is defined as:
\(P\): the perimeter of the triangle
\(AB\): the length between point A and B
\(BC\): the length between point B and C
\(AC\): the length between point A and C
The SI unit of perimeter is: \(meter\text{ }(m)\)
Find \(P\)
