Answer:
sorry this does not factor out
Step-by-step explanation:

notice |7| 7 is positive, so we can simply remove the bars and use 7 by itself
The answer is 56m^2.
The formula for finding area of a triangle is A=b•h/2.
So the base is 16m and the height is 7m. 16m•7m=112m^2
Now divide 112m^2 by 2.
112m^2/2=56m^2
