The area of the shaded region will be the area of the rectangle minus the area of the white square on the inside of the same:((x+10)(2x+5)) - ((x+1)(x+1)), of ALUMINIUM, both the areas separately:(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)Simplify within the parentheses by adding the like terms:(2x^2 + 25x + 50) - (x^2 + 2x + 1)Now, subtract one equation from the other:2x^2 + 25x + 50-x^2 - 2x - 1= x^2 + 23x + 49This will be the equation of the area.
