First you need to find the total length of the fence: 2 lengths and 2 widths

anonymous · Answer

2(72) + 2(104)

anonymous · Answer

Which is 352

anonymous · Answer

Now we have to find how many 8 foot sections we have in this length: 352/8= 44

anonymous · Answer

And how much is 44 sections of fence at $11.45 a section? Thats your answer :)

anonymous · Answer

It is $503.80. Thank you so much!
