A garden that is 24 ft by 14 ft has a walkway that is 4 ft wide around it. What is the amount of fencing needed to surround the
SCORPION-xisa [38]
The garden is 24 ft by 14 ft
The walkway stretches all the way around the garden
The walkway is 4 ft wide

Perimeter is found by adding the length of the four sides so this would be 24 + 14 + 24 + 14 = 76
24 + 24 = 48
14 + 14 = 28
48 + 28 = 76

I don't know for sure but I think the length would be 34 using the length formula
p / 2 - w
so 76 / 2 - 4
38 - 4
34

I have no clue though. A picture would make it easier
