Answer:
[tex]P = 74\ meters[/tex]
Step-by-step explanation:
By definition the perimeter of a rectangle is the sum of the lengths of its 4 sides.
The formula for calculating the perimeter of a rectangle is as follows:
[tex]P = 2w + 2l[/tex]
Where P is the perimeter, w is the width and l is the length.
In this case we want to find P and we know that:
[tex]w =16\ meters[/tex]
[tex]l =21\ meters[/tex]
Therefore:
[tex]P = 2(16) + 2(21)[/tex]
[tex]P = 32 + 42[/tex]
[tex]P = 74\ meters[/tex]
