Perimeter of a Rectangle: Applying the formula

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

$AB=CD=2$

$AD=BC=7$

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

$2+7+2+7=4+14=18$

In the drawing, we have a rectangle, although it is not placed in its standard form and is slightly rotated,
but this does not affect that it is a rectangle, and it still has all the properties of a rectangle.
 
The perimeter of a rectangle is the sum of all its sides, that is, to find the perimeter of the rectangle we will have to add the lengths of all the sides.
We also know that in a rectangle the opposite sides are equal.
Therefore, we can use the existing sides to complete the missing lengths.
 
4.8+4.8+12+12 =
33.6 cm

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

$AD=BC=9.5$

$AB=CD=1.5$

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

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

To solve this problem, we'll start by identifying the given dimensions of the rectangle: the length $l = 18$ and the width $w = 2$.

Next, we apply the perimeter formula for a rectangle, which is given by:

$P = 2(l + w)$

Substitute the given values for the length and width into the formula:

$P = 2(18 + 2)$

Calculating further, we find:

$P = 2 \times 20 = 40$

Thus, the perimeter of the rectangle is $40$. Among the provided answer choices, this corresponds to choice 1.

Since in a square all sides are equal to each other, all sides are equal to 8 cm.

Now we can calculate the perimeter:

$8\times4=32$
