The area of the triangular section is 12 square units and the area of the entire figure is 60 square units
How to determine the area?
The dimension of the triangular section is:
Base = 12 - 6 = 6 units
Height = 4 units
So, the area is:
Area = 0.5 * Base * Height
This gives
Area = 0.5 * 6* 4
Area = 12 square units
The area of the entire figure is then calculated as;
Area = Triangle + Rectangle
This gives
Area = 12 + 12 * 4
Evaluate
Area = 60
Hence, the area of the triangular section is 12 square units and the area of the entire figure is 60 square units
