The area of the triangle is expressed as 2.718cm²
<h3>Area of a triangle</h3>
The formula for calculating the area of a triangle is expressed as:
A = 0.5absinФ
- a and b are the sides
- Ф is the angle
Given the following
- p = 2.5 cm
- n = 2.3 cm and;
- ∠O=71°
Substitute the given parameters to have:
Area = 0.5(2.5)(2.3)sin71
Area = 2.718cm²
Hence the area of the triangle is expressed as 2.718cm²
