Sari 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?(1 point)
To create a rectangular dog run space, you need 2 sides of length L and 2 sides of length W. In this case, Sari wants the width to be 8 feet.
The formula for the perimeter of a rectangle is given by P = 2(L + W), where L is the length and W is the width.
Since the perimeter of the dog run space is given as 40 feet, we can substitute these values:
40 = 2(L + 8)
Dividing both sides of the equation by 2:
20 = L + 8
Finally, subtracting 8 from both sides:
L = 12
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 information given.
We know that Sari has 40 feet of fencing to go around the outside of the dog run. Let's break it down:
- There are two lengths and two widths of the rectangular dog run.
- Each length will have the same length of fencing.
- Each width will have the same length of fencing.
Since Sari wants to make the width 8 feet, it means that the two widths of the dog run will use a total of 2 * 8 = 16 feet of fencing.
To find the remaining fencing for the lengths, we subtract the width fencing from the total fencing:
40 - 16 = 24 feet
This 24 feet will now be used for the two lengths, so each length will have a length of 24 / 2 = 12 feet.
Therefore, the length of the rectangular dog run space will be 12 feet.
To find out the length of the dog run space, you can subtract twice the width from the total length of the fencing.
Given:
Total fencing = 40 feet
Width = 8 feet
To find the length:
Length = Total fencing - 2 * Width
Length = 40 feet - 2 * 8 feet
Length = 40 feet - 16 feet
Length = 24 feet
Therefore, the length of the dog run space will be 24 feet.
