  2. Area - Wikipedia

    en.wikipedia.org/wiki/Area

    That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: [1] [2] A = s 2 (square). The formula for the area of a rectangle follows directly from the basic properties of area, and is sometimes taken as a ...

  3. Square - Wikipedia

    en.wikipedia.org/wiki/Square

    The area of a square is the product of the length of its sides. The perimeter of a square whose four sides have length is = and the area A is =. [1] Since four squared equals sixteen, a four by four square has an area equal to its perimeter.

  4. Equable shape - Wikipedia

    en.wikipedia.org/wiki/Equable_shape

    An area cannot be equal to a length except relative to a particular unit of measurement. For example, if shape has an area of 5 square yards and a perimeter of 5 yards, then it has an area of 45 square feet (4.2 m 2) and a perimeter of 15 feet (since 3 feet = 1 yard and hence 9 square feet = 1 square yard).

  9. Square (algebra) - Wikipedia

    en.wikipedia.org/wiki/Square_(algebra)

    The square of an integer may also be called a square number or a perfect square. In algebra, the operation of squaring is often generalized to polynomials, other expressions, or values in systems of mathematical values other than the numbers. For instance, the square of the linear polynomial x + 1 is the quadratic polynomial (x + 1) 2 = x 2 ...
