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 find the length, we need to subtract the width from the perimeter of the rectangle.
The perimeter of a rectangle is given by the formula: perimeter = 2(length + width)
In this case, the perimeter is 40 feet, and the width is 8 feet.
40 = 2(length + 8)
Divide both sides of the equation by 2:
20 = length + 8
Subtract 8 from both sides of the equation:
12 = length
Therefore, the length will be 12 feet.
To find the length of the rectangular dog run space, we can subtract twice the width from the total amount of fencing.
Given:
Total fencing = 40 feet
Width = 8 feet
Length = Total fencing - 2 * Width
Length = 40 feet - 2 * 8 feet
Length = 40 feet - 16 feet
Length = 24 feet
Therefore, the length of the rectangular dog run space will be 24 feet.
To find the length of the rectangular dog run space, we can use the formula for the perimeter of a rectangle, which is:
Perimeter = 2 * (Length + Width)
In this case, we know that the Width is 8 feet, and the Perimeter is given as 40 feet. We can plug these values into the formula and solve for the Length.
40 = 2 * (Length + 8)
First, let's simplify the equation by removing the multiplication:
40 = 2 * Length + 16
Next, let's isolate the term with the Length:
2 * Length = 40 - 16
2 * Length = 24
Now, let's solve for Length by dividing both sides of the equation by 2:
Length = 24 / 2
Length = 12
Therefore, the length of the rectangular dog run space will be 12 feet.
