Calculus is an inaccurate measurement of area

Calculus is actually an inaccurate representation of a mathematical solution to the area of a shape. The very premise of calculus is incorrect the very concept that Infinity can derive the area within a shape is fundamentally inaccurate. Because it will always leave an area of the shape unmeasured. So using calculus as an accurate measurement of an area within a shape is false. Because the area within a shape is finite and cannot be solved with an equation that uses a component that measures its proximity through infinity. It will always be an approximation of its area but not it's actual area. In that there is a finite area within a shape there is a finite mathematical solution in the solving of its area. All that calculus does is measure an infinitely smaller area of a shape that is infinitely left unmeasured undefined. To somehow equate the infinity measures the area of a shape with its eventual solution is false. The solution to the measurement within a shape is a finite equation that defines the measurement of the finite area that measures the finite area within it.
