How to square

Squaring is an operation, e.g., the square of a denotes a x a, abbreviated as a?, or a x a (a square of a multiplied by a equals a to the power of 2), e.g., 4 x 4 = 16, 8 x 8 = 64, and the square symbol is 2.

Formulas on calculating squares:

Rectangle: ? {Area of rectangle = length x width}

Square: ? {Square area = side length x side length}

Parallelogram: ? {Parallelogram area = base x height}

Triangle: ? {Triangle area = base x height ÷ 2}

Trapezoid: ? {Trapezoid area = (top base + bottom base) x height ÷ 2}

Circle (square circle): ? {Circle (square circle) area = circumference x radius x radius}

Example:

The formula for the area of a rectangle is that what the length times the width equals is the area, and the unit of the area is the square, not the area of the square as you said.?

For example: the length and width of a rectangle are 8 meters and 5 meters respectively, the area of the rectangle is: 8 meters * 5 meters = 40 (square meters).

Unit conversion: 1 ㎡ (1 square meter) = 100 dm? (100 square decimeters) = 10,000 cm? (10,000 square centimeters) = 1,000,000 mm? (1,000,000 square millimeters) = 0.0001 hectares = 0.000001km? (0.000001 square kilometers) = 0.01 metric acres = 0.0002471054 acres = 0.0000003861 square miles = 10.763910417 square feet = 0.0015 acres
