Sara is creating a dog-run space in her backyard. She has 40 feet of fencing to go around outside and she wants to make it rectangular with a width of 8 feet. What will the length be, in feet?
3 answers
The length of the dog-run space R is the perimeter P minus twice the width W, or R=P-2W. Thus, substituting in the given length and width labels, we have R=40-2*8=<<40-2*8=24>>24 feet. Answer: \boxed{24}.
That was wrong
Apologies for the mistake.
Let's calculate the perimeter of the dog-run space. The perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width.
Given that the width is 8 feet and the perimeter is 40 feet, we can write the equation as 40 = 2L + 2(8).
Expanding the equation, we get 40 = 2L + 16.
Subtracting 16 from both sides of the equation, we have 24 = 2L.
Dividing both sides of the equation by 2, we get L = 12.
Therefore, the length of the dog-run space is 12 feet. Answer: \boxed{12}.
