Area of parallelograms
The area of a A parallelogram has opposite sides which are both parallel and equal in length. can be calculated using the following formula.
Remember, the height must be the perpendicular height, measured across the shape.
Example
Calculate the area of the parallelogram.
Area = \(9 \times 6 = 54~\text{cm}^2\)
The formula for the area of a parallelogram can be used to find a missing length.
Question
Calculate the width of the base of the parallelogram:
Area = 40 cm2
\(5 \times b = 40~\text{cm}^2\)
\(b = 40 \div 5 = 8~\text{cm}\)
