Perimeter is the sum of the length of the sides used to make the given figure. The length and the width of the rectangle are 60 meters and 20 meters, respectively.
<h3>What is the perimeter?</h3>
Perimeter is the sum of the length of the sides used to make the given figure.
Let the width of the rectangle be represented by x.
Given that the pen should be three times as long as it is width. Therefore, the dimensions of the rectangle can be written as,
Width of the rectangle = x
Length of the rectangle = 3x
Also, it is given that the perimeter of the rectangle should be equal to 160 meters, therefore, we can write,
Perimeter = 2(Length + Width)
160 = 2(3x + x)
160 = 2(4x)
160 = 8x
x = 160/8
x = 20 meters
Now, the dimensions of the rectangle can be written as,
Length = 3x = 3 × 20 meters = 60 meters
Width = x = 20 meters
Hence, the length and the width of the rectangle are 60 meters and 20 meters, respectively.
