Calculate Rectangle Perimeter: Area = 45 Square Units

Question

If the area of the rectangle below is equal to 45.

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

00:14 We'll 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 rhombus all opposite sides are parallel and equal to each other, we can claim that:

$AC=DB=5$

$AB=CD=9$

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

$5+9+5+9=10+18=28$
