Answer:
273.7
Step-by-step explanation:
first fine the sides that isn't the base.
triangle area formula: (b*h)/2
(14*9)/2 = 63
since there are 3 sides you multiply this by three.
63*3=189
then find the base.
same formula since its a triangle.
(12.1*14)/2 = 84.7
now add them both up:
84.7+189 = 273.7
hope this helps!
first step is to subtract 21 from both sides
2m+21-21=3-21
2m=-18
2m/2 and -18/2
m=-9
So the final answer is m=-9 (negative nine equals m)
