Question

The length of your rectangular backyard is 275 feet and the width is 125 feet. You want to enclose the backyard with chain link fence that is $1.25 per foot. Calculate the total cost of the fencing required to enclose the backyard. Could you tell how you got as well :)

Answer 1

total length = perimeter of the yard = 2*275 + 2*125 =  800 feet

total cost of the fence = 800 * 1.25 = $1000

Answer 2

You need to find the perimeter of the backyard to figure out how much fencing you need. To do this you can add 275 + 275 + 125 + 125. This is 800. From here, you can multiply 800 by $1.25 to find how much it will be to buy enough fencing. The final answer is $1000 for the fencing.
