Calculate Rectangle Perimeter: Given Sides 1.5 cm and 9.5 cm

Question

Look at the rectangle below.

Side DC has a length of 1.5 cm and side AD has a length of 9.5 cm.

What is the perimeter of the rectangle?

00:00 Calculate the perimeter of rectangle ABCD

00:03 Opposite sides are equal in a rectangle

00:12 The perimeter of the rectangle equals the sum of its sides

00:22 Let's substitute appropriate values and solve to find the perimeter

00:30 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:

$AD=BC=9.5$

$AB=CD=1.5$

Now we can add all the sides together and find the perimeter:

$1.5+9.5+1.5+9.5=19+3=22$
