Answer:
![8x^{2} +3x+6](https://tex.z-dn.net/?f=8x%5E%7B2%7D%20%2B3x%2B6)
Step-by-step explanation:
To find total area, the farmer needs to find add the areas of the two plots.
Area equation can be obtained by summing eqtn 1 to eqtn 2 as below to obtain a single polynomial expression for the area.
a1=![3x^{2} +7x-5](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B7x-5)
a2=![5x^{2} -4x+11](https://tex.z-dn.net/?f=5x%5E%7B2%7D%20-4x%2B11)
Therefore total area is given by:-
![(3x^{2} +7x-5)+(5x^{2} -4x+11)\\=8x^{2} +3x+6](https://tex.z-dn.net/?f=%283x%5E%7B2%7D%20%2B7x-5%29%2B%285x%5E%7B2%7D%20-4x%2B11%29%5C%5C%3D8x%5E%7B2%7D%20%2B3x%2B6)
