The perimeter of this rectangle is equal to 46.3 meters.

Given the following data:

  • Area of rectangle = 45.15 square meters.
  • Length of rectangle = 21 meters.

To determine the perimeter of this rectangle:

First of all, we would calculate the width of the rectangle by using this formula:

[tex]A = Length \times Width\\\\45.15=21 \times W\\\\W=\frac{45.15}{21}[/tex]

Width, W = 2.15 meters.

Now, we can determine the perimeter of this rectangle:

Mathematically, the perimeter of a rectangle is given by the formula;

[tex]P=2(L+W)\\\\P=2(21+2.15)\\\\P=2(23.15)[/tex]

Perimeter = 46.3 meters.
