Rectangle Perimeter Calculation: Finding the Distance Around a 66-Square-Unit Rectangle

Question

The area of the rectangle below is equal to 66.

Calculate the perimeter of the rectangle.

00:00 Find the perimeter of the rectangle

00:03 The perimeter of the rectangle equals the sum of its sides

00:10 Opposite sides are equal in a rectangle

00:16 Let's substitute appropriate values according to the given data and solve for the perimeter

00:22 And this is the solution to the problem

Since in a rectangle every pair of opposite sides are equal to each other, we can claim that:

$\text{AB=CD}=11$

$AC=BD=6$

Now let's calculate the perimeter by adding all the sides together:

$6+11+6+11=12+22=34$
