Rectangle with Area 8: Calculate the Complete Perimeter

Question

The area of a rectangle is equal to 8.

Calculate the perimeter of the rectangle.

00:00 Determine the perimeter of the rectangle

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

00:08 Opposite sides are equal in a rectangle

00:14 Substitute the relevant values into the formula according to the given data and proceed to solve for the perimeter

00:18 This is the solution

According to the properties of the rectangle, all pairs of opposite sides are equal.

$AB=CD=8$

$AC=BD=2$

Now we calculate the perimeter of the rectangle by adding all the sides:

$4+4+2+2=8+4=12$
