Answer :
The width of the rectangular pen is equal to 14 feet.
Given the following data:
- Perimeter of rectangle = 78 feet.
- Length = 25 feet.
To calculate the width of the rectangular pen:
Formula for the perimeter of a rectangle.
Mathematically, the perimeter of a rectangle is given by the formula;
[tex]P=2(L+W)[/tex]
Where:
- P is the perimeter of a rectangle.
- L is the length of a rectangle.
- W is the width of a rectangle.
Substituting the parameters into the formula, we have;
[tex]78=2(25+W)\\\\78=50+2W\\\\2W=78-50\\\\2W=28\\\\W=\frac{28}{2}[/tex]
Width, W = 14 feet.
