Calculate Parallelogram Perimeter: Using Side Lengths 4 and 6

Question

Calculate the perimeter of the given parallelogram:

00:00 Calculate the perimeter of the parallelogram

00:06 Opposite sides are equal in a parallelogram

00:16 Let's substitute the side value

00:25 These sides are also opposite therefore equal

00:32 Let's substitute the side value

00:38 The perimeter of the parallelogram equals the sum of its sides

01:02 Let's substitute appropriate values and solve for the perimeter

01:13 And this is the solution to the question

As is true for a parallelogram every pair of opposite sides are equal:

$AB=CD=6,AC=BD=4$

The perimeter of the parallelogram is equal to the sum of all sides together:

$4+4+6+6=8+12=20$
