Frequently Asked Questions
Area of Quadrilaterals
Learn how to find the area of different quadrilaterals.
Square
Area = side × side
A = l²
Rectangle
Area = base × height
A = b × h
Parallelogram
Area = base × perpendicular height
A = b × h
Trapezium
Area = average of parallel sides × height
A = ((a + b) ÷ 2) × h
Rhombus
Area = diagonal 1 × diagonal 2 ÷ 2
A = (d1 × d2) ÷ 2
Kite
Area = diagonal 1 × diagonal 2 ÷ 2
A = (d1 × d2) ÷ 2
Area measures the amount of space inside a shape.
Area of Quadrilaterals
Learn how to calculate the area of quadrilaterals including squares, rectangles, parallelograms, trapeziums, rhombuses and kites.
Area is the amount of space inside a 2D shape and is measured in square units such as cm² or m².
Square
Area = side × side (A = l × l)
Rectangle
Area = base × height (A = b × h)
Parallelogram
Area = base × perpendicular height (A = b × h)
Trapezium
Area = ((a + b) ÷ 2) × h
Rhombus
Area = (d1 × d2) ÷ 2
Kite
Area = (d1 × d2) ÷ 2
Area measures the space inside a shape.
