area formula
Surface calculation method
An area formula is a mathematical expression for calculating the two-dimensional space enclosed by a shape.
Common examples include length times width for rectangles, pi times radius squared for circles, and one-half base times height for triangles.
I couldn't remember the area formula for a trapezoid.
