Step-by-step explanation:

The field that is being fenced in has two 30 foot sides and 2 18 foot sides. The reason they are 18 is because there are 3 feet in a yard. You would then add all 4 sides together, equaling your perimeter.

-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
