Calculating Area of Common Shapes | Formulas for Squares, Rectangles, Triangles, and Circles

area

The term “area” in mathematics refers to the amount of space or surface covered by a two-dimensional shape

The term “area” in mathematics refers to the amount of space or surface covered by a two-dimensional shape. It is a measure of the size or extent of a shape’s surface. The area of a shape is usually expressed in square units, such as square centimeters (cm²), square meters (m²), or square inches (in²).

The formula to calculate the area of various common shapes is as follows:

1. Square: The area of a square is given by the formula A = s × s, where “s” represents the length of one side of the square.

2. Rectangle: The area of a rectangle is calculated using the formula A = length × width, where “length” represents the longer side and “width” represents the shorter side of the rectangle.

3. Triangle: The area of a triangle can be found using various formulas depending on the given information. A common formula is A = 0.5 × base × height, where “base” represents the length of the triangle’s base and “height” represents the perpendicular distance from the base to the opposite vertex.

4. Circle: The area of a circle is given by the formula A = π × r², where “π” represents the mathematical constant pi (approximately 3.14159) and “r” represents the radius of the circle.

It is important to note that the units for the dimensions of a shape should be consistent when calculating the area. For example, if the length of a rectangle is given in meters, the width should also be in meters to ensure the area is expressed in square meters.
