Area of a rectangle 


AB = DC = width = w AD = BC = h = height ExampleABCD is a rectangle of width w = 5 cm and of height h = 2 cmArea A of the rectangle = w x h = 5 x 2 = 10 cm² Calculate the area of a rectangle 
RectangleA rectangle is a foursided polygon with opposite sides equal in length and four right angles. Its properties include a straightforward area formula: A = length × width.The sum of interior angles is always 360 degrees. Diagonals bisect each other and create congruent triangles. Rectangles can be inscribed in circles, with the diagonal as the diameter. Properties of a rectangleEqual opposite sides: a rectangle has two pairs of opposite sides that are equal in length.Right angles: all four angles of a rectangle are right angles (90 degrees). Opposite sides are parallel: the opposite sides of a rectangle are parallel to each other. Diagonals are equal: the diagonals of a rectangle are congruent and bisect each other. Interior angles sum to 360 degrees: the sum of the interior angles of a rectangle is always 360 degrees. Diagonals bisect each other: each diagonal of a rectangle divides the rectangle into two congruent rightangled triangles. Symmetry: rectangles exhibit bilateral symmetry, meaning they can be divided into two equal halves along a line. Inscribed in circles: a rectangle can be inscribed in a circle, with the diagonal as the diameter. ExamplesYou can find below ten examples of calculating the area of a rectangle. These examples demonstrate the application of the area formula for rectangles across different units of measurement.Example 1:Length = 5 unitsWidth = 8 units Area = Length × Width = 5 × 8 = 40 square units Example 2:Length = 12 metersWidth = 6 meters Area = Length × Width = 12 × 6 = 72 square meters Example 3:Length = 9 feetWidth = 3 feet Area = Length × Width = 9 × 3 = 27 square feet Example 4:Length = 15 cmWidth = 10 cm Area = Length × Width = 15 × 10 = 150 square centimeters Example 5:Length = 7.5 inchesWidth = 4 inches Area = Length × Width = 7.5 × 4 = 30 square inches Example 6:Length = 20 yardsWidth = 5 yards Area = Length × Width = 20 × 5 = 100 square yards Example 7:Length = 18 metersWidth = 2.5 meters Area = Length × Width = 18 × 2.5 = 45 square meters Example 8:Length = 14 feetWidth = 7 feet Area = Length × Width = 14 × 7 = 98 square feet Example 9:Length = 25 cmWidth = 3.5 cm Area = Length × Width = 25 × 3.5 = 87.5 square centimeters Example 10:Length = 16 inchesWidth = 9 inches Area = Length × Width = 16 × 9 = 144 square inches
