Area Formulas for Quadrilaterals
This page focuses on the area formulas for various quadrilaterals, providing visual representations alongside each formula.
-
Rectangle: P = a · b Where 'P' is the area, 'a' and 'b' are the lengths of the sides.
-
Square: P = a² Where 'a' is the length of a side.
-
Parallelogram: P = a · h₁ or P = b · h₂ Where 'h₁' and 'h₂' are the heights corresponding to sides 'a' and 'b' respectively.
-
Rhombus: P = (d₁ · d₂) / 2 Where 'd₁' and 'd₂' are the diagonals of the rhombus.
Alternatively: P = a² / sin α Where 'a' is the side length and 'α' is one of the angles.
-
Trapezoid: P = / 2 Where 'a' and 'b' are the parallel sides and 'h' is the height.
Example: For a rhombus with diagonals of length 6 cm and 8 cm, the area would be calculated as: P = (6 cm · 8 cm) / 2 = 24 cm²
Highlight: The trapezoid formula can be remembered as "half the sum of the parallel sides times the height".
