Answer
Total cost of fencing is $684
Work Step by Step
We first find the perimeter of the rectangular lot
The perimeter is equal to the sum of the lengths of its sides
perimeter = 120 + 120 + 60 + 60
perimeter = 360 feet
one foot of fencing cost 1.90
360 feet costs 1.90 $\times$ 360
Total cost = 1.90 $\times$ 360
Total cost = 684
