Area = length x width
Because the width is less than 1 foot the area would be less than 8 square feet.
Answer: smaller than
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that

An arc is a part of total circumference of circle and length of that arc is the measurement of linear distance.
Since we know the formula for "Length of an arc " , we get

Hence, Option 'C' is correct.
General Idea:
(i) Assign variable for the unknown that we need to find
(ii) Sketch a diagram to help us visualize the problem
(iii) Write the mathematical equation representing the description given.
(iv) Solve the equation by substitution method. Solving means finding the values of the variables which will make both the equation TRUE
Applying the concept:
Given: x represents the length of the pen and y represents the area of the doghouse
<u>Statement 1: </u>"The pen is 3 feet wider than it is long"

------
<u>Statement 2: "He also built a doghouse to put in the pen which has a perimeter that is equal to the area of its base"</u>

------
<u>Statement 3: "After putting the doghouse in the pen, he calculates that the dog will have 178 square feet of space to run around inside the pen."</u>

------
<u>Statement 4: "The perimeter of the pen is 3 times greater than the perimeter of the doghouse."</u>

Conclusion:
The systems of equations that can be used to determine the length and width of the pen and the area of the doghouse is given in Option B.

Dependent variable is the variable that changes due to the independent variable, independent variable is the variable that scientists change on purpose.
