Area Formulas Explained
Square Area
The area of a square is calculated by squaring the length of one of its sides. All sides of a square are equal in length.
Rectangle Area
The area of a rectangle is calculated by multiplying its length by its width. Opposite sides of a rectangle are equal.
Parallelogram Area
The area of a parallelogram is calculated by multiplying its base by its height. The height is the perpendicular distance between the base and its opposite side.
Triangle Area
The area of a triangle is calculated by multiplying its base by its height and then dividing by two.
Circle Area
The area of a circle is calculated by multiplying π (pi, approximately 3.14159) by the square of the radius.
Trapezoid Area
The area of a trapezoid is calculated by adding the two parallel sides (bases), multiplying by the height, and dividing by two.
