Calculate Rectangle Perimeter: Area = 78, Dimensions 13 × 6

Question

If the area of a rectangle is 78.

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 problem

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

$AB=CD=13$

$AC=BD=6$

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

$6+13+6+13=12+26=38$
