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

The equation for finding perimiter is 2(l+w). So, 2(275+125)=P

theDeviliscoming:

The total cost of fencing the yard is \[P \times $1.25\]
