Hey there! I'm happy to help!
The perimeter is the distance around the rectangle.
In a rectangle, there are two pairs of opposite sides, and those opposite sides are equal. They are known as the length and the width.
In a rectangle, you have two sides that have the same length and two that have the same width. If you add these all up, you get the perimeter.
If our length is L and our width is W, we can write this equation.
P=2L+2W
So, we can plug in our lengths and widths to find the perimeter!
P=2(4.5)+2(8.2)
P=9+16.4
P=25.4
Therefore, our perimeter is 25.4 cm.
Have a wonderful day! Feel free to message me if you have any questions! :D
