A farmer wants to build a small, rectangular pen next to a barn. She has 55 feet of fence available and needs the length of the pen to be three times the
width. If the barn forms the fourth side of the pen as shown in the figure
below, what dimensions (length and width) should the pen be so that all 55 feet
of fence are used with the other three sides? *You must use a variable to
write an equation, show your work, and label your correct answers with the
correct units for full credit.
Equation: _

Width _

Length _

Units for both width and length _

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
