Answer:
area = 13.8 cm²
Step-by-step explanation:
The area of the triangle can be calculated using the following rule:
area of triangle = (1/2) * base * height
In the given:
base of triangle = 6.9 cm
height of triangle = 4 cm
Substitute with the givens in the above equation to get the area as follows:
Area = (1/2) * (6.9) * (4)
Area = 13.8 cm²
Hope this helps :)
