Calculate Parallelogram Perimeter: Using Side Lengths 7 and 10

Question

Calculate the perimeter of the given parallelogram.

00:00 Calculate the perimeter of the parallelogram

00:03 Opposite sides are equal in a parallelogram

00:08 Let's substitute the side value

00:15 These sides are also opposite therefore equal

00:21 Let's substitute the side value

00:32 The perimeter of the parallelogram equals the sum of its sides

00:50 Let's substitute appropriate values and solve for the perimeter

00:59 And this is the solution to the question

As is true for a parallelogram each pair of opposite sides are equal and parallel,

Therefore it is possible to argue that:

$AC=BD=7$

$AB=CD=10$

Now we can calculate the perimeter of the parallelogram by adding together all of its sides:

$10+10+7+7=20+14=34$
