Rectangle Perimeter Calculation: Area = 18 Square Units

Question

If the area of the rectangle below is equal to 18.

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

00:09 Opposite sides are equal in a rectangle

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

00:20 And this is the solution to the question

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

$AB=CD=6$

$AC=BD=3$

To calculate the perimeter of the rectangle, we add all the sides together:

$3+6+3+6=6+12=18$
