Casey was building a rectangular pen for his pigs. he has 62 feet of fencing. the length of his pen is 9 feet longer that the width. write an equation and solve to find the dimensions of the pen

For this problem we need to find what perimeter is equal to 62 feet. To find perimeter of a rectangle we do:

where p = perimeter, w = width, and l = length
This problem says that the length is 9 feet longer than the width, so the length would be: 

Now we know what the perimeter and length is, so we can put those into the equation above. This is what it will look like:

and that will solve like so:


Now that we know the width we can plug it into our first equation to find the length:


Your width is 11 feet and your length is 20 feet.
