1275 is the area of the coposite shape.
The denominator. Say for instance, you have 4/12 and 1/6. They are equivalent.
a+2a=3a
3a=3a
The answer is infinetly many solutions.
Y=-2x+3 (could be any y-int as long as it has the same slope)
This line is parallel to the original line so they never intersect
Therefore the answer is no solution
The way I would do it is by rounding 8.91 up to 9 and I would round 34,871.081 up to 35,000.
9*35,000=315,000
Hopefully I was able to help in some way.
