Question

The Andersons are buying a new home. They need to fence the yard because they have a dog. The yard is 72 feet by 120 feet. Each fencing section is 8 feet. How many sections will they need?

Answer 1

Let's find the perimeter of the yard first (amount that needs to be fenced):
72 + 102 + 72 + 102 = 348 ft. 

Now we can find the amount of fencing sections needed 
348 ft. ÷ 8 ft. sections = 43.5 sections

The answer is 43.5 sections (may need to round up to 44 sections if the sections need to be whole)
