Mathematics

We know the area of a rectangle is length times width, and the area of a triangle is one-half base times height. So to find the area of the shaded area, we need to subtract the area of the rectangle from the area of the triangle.

$\frac{1}{2} (2x+5)(x+6) - x(x+1)$

$\frac{2x^2+12x+5x+30}{2} -x^2-x$

$x^2 + \frac{17x}{2} + 15 - x^2 - x$

$\frac{15x}{2} + 15$
