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 :)

Answer:Second Step
Step-by-step explanation:
On the right side in step two you added -3b-15b, and ended up with -12b. This is incorrect. -3b-15b is actually -18b
Step-by-step explanation:
A=½bh
A=½(4•3)
A=½(12)
A=6 units sq
9 times 5 equals 45 so yes
