Area of triangle
Watch this video to learn how to calculate the area of a triangle.
To be able to calculate the Area is the measurement of the amount of space inside a surface. of a The simplest two-dimensional shape is the triangle, a three-sided shape with three angles., you need to know two sides and the included angle.
\(Area = \frac{1}{2} ab \sin C\)
Example
Find the area of triangle ABC.
\(Area = \frac{1}{2} \times bc \times \sin A\)
\(Area = 0.5 \times 3 \times 7 \times \sin (35^\circ )\)
\(Area = 6.02255...\)
\(Area = 6.02c{m^2}(to\,2\,d.p.)\)
