Answer:
Tthe area of the shaded region is
![(x^(2)-3x+36)\ unit^(2)](https://img.qammunity.org/2020/formulas/mathematics/high-school/m8fgroxjf5g9joxkp4rg1dqwqn4pjw6qz0.png)
Explanation:
we know that
To find the area of the shaded region (blue region), subtract the area of the smaller rectangle from the area of the larger square
so
Find the area of the larger square
![A=(x+1)^(2)=(x^(2)+2x+1)\ unit^(2)](https://img.qammunity.org/2020/formulas/mathematics/high-school/vmzl6ewrxlgoh36e4ule0jcxbudahpeaiw.png)
Find the area of the smaller rectangle
![A=5(x-7)=(5x-35)\ unit^(2)](https://img.qammunity.org/2020/formulas/mathematics/high-school/g2z1i8k989zdnsc7724ghfwy7g4258jdxl.png)
Subtract the polynomials
![(x^(2)+2x+1)-(5x-35)=(x^(2)-3x+36)\ unit^(2)](https://img.qammunity.org/2020/formulas/mathematics/high-school/z30eac9l3mtex7siueb2kmh1clsyzyamaw.png)
