What is a Triangle?
This is defined as a polygon which has three edges and three vertices. It also has three sides with the hypotenuse being the longest.
The area is 1/2 × base × height.
Area of triangles =
- 1/2 × 3 × 3 = 4.5square units
- 1/2 × 3 × 3 = 4.5square units
- 1/2 × 5 × 2 = 4 square units.
The total area = 4.5square units + 4.5square units + 4 square units = 13 square units.
