A farmer is building fence around a triangular area. The cost of building the shortest side is ${35x}$ dollars, where $x$ stands for the length of the side in feet. The cost of building the other two sides can be modeled by ${6x^{2}-3.5x+45}$ dollars and ${5x^{3}+0.5x+25}$ dollars, respectively. What’s the total cost of building fence for all three sides? The cost of building fence for all three sides would be dollars.
