A two-dimensional geometric shape is a part of a plane that is enclosed by straight or curved lines, does not contain any holes and remains intact even if one of its points is removed.
The area is a function that assigns a positive number to all two-dimensional geometric shapes with the following conditions:
1. The area of the unit square is 1.
2. The area of congruent geometric shapes is equal.
3. If we divide a geometric shape into several parts, the sum of the areas of the parts is equal to the area of the original geometric shape.
The area of a rectangle is the product of its width and height.
The area of a triangle is half the product of its base length and its height. (This formula derives from the formula of the area of the parallelogram.)
The area of a parallelogram is the product of its base length and height.
The area of a trapezoid is the product of half the sum of the parallel sides and its height.
The area of a circle can be calculated by multiplying the square of its radius with π (pi).
The area of a circular sector can be calculated from the area of the full circle, using the ratio of the central angle to the full angle (360°).
