Given the parallelogram:
Calculate the perimeter of the parallelogram.
Because a parallelogram has two pairs of opposite sides! If one side is 5, then its opposite side is also 5. Same for the 4-unit sides. So you have: 5 + 4 + 5 + 4, which equals 2(5 + 4).
Opposite sides are the ones that don't touch each other. In the diagram, sides AB and CD are opposite (both length 5), and sides AC and BD are opposite (both length 4).
The shape doesn't matter for perimeter! Whether it's a rectangle, rhombus, or slanted parallelogram, the perimeter formula stays the same: P = 2(a + b).
Be careful! Sometimes diagrams only label two adjacent sides because the opposite sides are automatically equal. Always use the given measurements and the parallelogram property.
No! Rectangles are special parallelograms, so they use the same perimeter formula: P = 2(length + width). The calculation method is identical.
