Siri is creating a dog run space in her backyard. She has 40 feet of fencing to go around the outside and she wants to make it rectangular with a width of 8 feet. What will the length be in feet?
To find the length of the dog run space, we need to subtract the width from the total perimeter of the rectangular space.
Total perimeter of the rectangular space = 2(length + width)
We are given that the width is 8 feet. Therefore,
Total perimeter = 40 feet
40 = 2(length + 8)
Divide both sides of the equation by 2:
20 = length + 8
Subtracting 8 from both sides of the equation:
length = 20 - 8 = 12 feet
Therefore, the length of the dog run space will be 12 feet.
To find the length of the rectangular dog run space, we can use the perimeter formula for a rectangle: 2(length + width).
Let's set up the equation with the given information:
40 feet = 2(length + 8 feet)
Next, we can simplify the equation and solve for length:
40 feet = 2(length + 8 feet)
Divide both sides by 2 to isolate the length:
20 feet = length + 8 feet
Now, subtract 8 feet from both sides to find the length:
20 feet - 8 feet = length
12 feet = length
Therefore, the length of the rectangular dog run space will be 12 feet.
To find the length of the dog run space, we can start by considering the formula for the perimeter of a rectangle, which is given by the equation:
Perimeter = 2*(Length + Width)
In this case, the perimeter is given as 40 feet, and the width is 8 feet. We can substitute these values into the equation and solve for the length:
40 = 2*(Length + 8)
First, let's simplify the equation by distributing the 2 to both terms inside the parentheses:
40 = 2*Length + 2*8
Simplifying further:
40 = 2*Length + 16
Next, let's isolate the term with the variable, 2*Length, on one side by subtracting 16 from both sides of the equation:
40 - 16 = 2*Length
24 = 2*Length
Finally, to find the value of Length, we can divide both sides of the equation by 2:
24/2 = Length
12 = Length
Therefore, the length of the dog run space will be 12 feet.
