Why area of region using integral calculus is negative? (Grade 12 Math) Step by Step) #shorts

When calculating the area of a region using integral calculus, the result can be negative if the function values are below the x-axis, because definite integrals compute the signed area between the curve and the x-axis; to obtain the actual geometric area, one must take the absolute value of the integral or split the integral into regions above and below the x-axis.
