The are of the region bounded by (in sq units) is:

Find the area of the region bounded above by $$y=e^x$$​, bounded below by $$y=x$$​, and bounded on the sides by $$x=0 \_0$$​ and $$x=1$$​.

Find the area under the curve y = $$3\text x^2$$ - 2x from x = 2 to x = 4.

The area enclosed by the curves $$y=x-1$$​ and $$y^2=2x+6$$​ is:
