Given the parallelogram:
Calculate the perimeter of the parallelogram.
To solve this problem, let's follow these steps:
Now, let's work through each step:
Step 1: From the diagram, we have two adjacent sides of the parallelogram: units and units.
Step 2: The formula for the perimeter of a parallelogram is given by .
Step 3: Substitute the values for and into the formula:
.
Therefore, the perimeter of the parallelogram is .
22
Given the parallelogram:
Calculate the perimeter of the parallelogram.
Because a parallelogram has two pairs of equal opposite sides! If one side is 8 units and the adjacent side is 3 units, then you have sides measuring: 8, 3, 8, 3. That's why we use .
Adjacent sides are next to each other, not across from each other. In the diagram, look for two sides that meet at a corner - those are your adjacent sides with lengths 8 and 3.
The method stays the same! Just identify the two different side lengths (adjacent sides), then use . Remember: opposite sides are always equal in parallelograms.
Yes, but it's more work! You'd get 8 + 3 + 8 + 3 = 22. The formula is faster and less prone to addition errors.
A rectangle is a special type of parallelogram where all angles are 90°. Both have opposite sides equal, so the perimeter formula works for both shapes!
