Rectangle Perimeter Calculation: Finding Distance Around a 63-Square-Unit Shape

Question

If the area of the rectangle below is 63.

Calculate the perimeter of the rectangle.

00:00 Find the perimeter of the rectangle

00:03 Opposite sides are equal in a rectangle

00:08 Substitute appropriate values according to the given data

00:13 The perimeter of the rectangle equals the sum of its sides

00:19 Substitute appropriate values according to the given data and solve to find the perimeter

00:44 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:

$AB=CD=9$

$AC=BD=7$

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

$7+9+7+9=14+18=32$
