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 given information tells us that one side is , and the adjacent side is .
Step 2: The perimeter of a parallelogram is given by the formula .
Step 3: We substitute the lengths we have:
Therefore, the perimeter of the parallelogram is .
36
Given the parallelogram:
Calculate the perimeter of the parallelogram.
Because a parallelogram has four sides, but opposite sides are equal! So you have two sides of length 10 and two sides of length 8. Instead of adding 10 + 8 + 10 + 8, it's easier to calculate 2 × (10 + 8).
You need both adjacent sides to find the perimeter. If you only know one side, you cannot calculate the perimeter unless the parallelogram is actually a special case like a rhombus (all sides equal).
No! You can use any two adjacent sides (sides that meet at a corner). In this problem, you could use 10 and 8, and the formula gives you 36.
Yes! Rectangles are special parallelograms, so they use the same perimeter formula. The only difference is that rectangles have right angles, but the side relationships are identical.
Think of a parallelogram as a "pushed rectangle" - the opposite sides stay parallel and equal. If you label the corners A, B, C, D going around, then AB = CD and AC = BD.
