A garden is 5 ft by 6 ft has a walkway that is 2 ft wide around it. What is the amount of fencing needed to surround the walkway?
Ms.sue how did you get 9 and 10
To find the amount of fencing needed to surround the walkway, we need to calculate the perimeter of the outer boundary of the walkway.
First, let's find the dimensions of the garden and walkway if we add the width of the walkway to both the length and width of the garden:
Length of the garden + 2 * Width of the walkway = 5 ft + 2 * 2 ft = 5 ft + 4 ft = 9 ft
Width of the garden + 2 * Width of the walkway = 6 ft + 2 * 2 ft = 6 ft + 4 ft = 10 ft
Now we have the dimensions of the outer boundary of the walkway, which is 9 ft by 10 ft.
To calculate the perimeter, we add the length and width of the outer boundary and double it since there are two sides of each length:
Perimeter = 2 * (9 ft + 10 ft) = 2 * 19 ft = 38 ft
Therefore, the amount of fencing needed to surround the walkway is 38 ft.
thank you
You are welcome.
P = 2L + 2W
P = (2 * 9) + (2 * 10)
P = 18 + 20
P = ?
