Given the parallelogram:
Calculate the perimeter of the parallelogram.
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem states that the lengths of sides AB and BC in the parallelogram are 11 and 7 units, respectively.
Step 2: The formula for the perimeter of a parallelogram is .
Step 3: Substituting the given lengths into the formula, we have:
.
Therefore, the perimeter of the parallelogram is units.

Given the parallelogram:
Calculate the perimeter of the parallelogram.
A parallelogram has four sides, but opposite sides are equal! So if you know two adjacent sides (11 and 7), you automatically know all four sides: 11, 7, 11, 7. The formula is a shortcut for adding all four.
You need both adjacent sides! Unlike squares or rectangles where knowing one side might be enough, parallelograms can have different side lengths. You must have both measurements to find the perimeter.
Rectangles are special parallelograms where all angles are 90°. The perimeter formula works the same way: .
Think "parallel = equal"! Since opposite sides are parallel, they're also equal in length. This makes counting easier: just double the sum of two adjacent sides.
Always use the given numerical values in the problem, not what you estimate from the drawing. Diagrams aren't always to scale, so trust the labeled measurements: 11 and 7 units.
