Are you sure you need integration for this?VVS2000 said:
You can, course, use integration to calculate the area of a square or a triangle - just for practice.VVS2000 said:

A surface integral is a mathematical concept used in multivariable calculus to calculate the area of a three-dimensional figure. It involves integrating a function over a two-dimensional surface, similar to how a regular integral calculates the area under a curve.
A surface integral involves integrating over a two-dimensional surface, while a regular integral integrates over a one-dimensional curve. Additionally, a surface integral can also involve a vector field, which adds a directional component to the calculation.
A surface integral is typically used when calculating the area of a three-dimensional figure with a curved surface. It is also useful for calculating the flux of a vector field through a surface.
The formula for a surface integral is ∫∫S f(x,y,z) dS, where S is the surface, f(x,y,z) is the function being integrated, and dS represents the differential element of the surface.
Surface integrals have many real-life applications, such as calculating the surface area of a 3D object for manufacturing purposes, determining the flow of a fluid through a curved pipe, and calculating the electric flux through a charged surface in physics.
