What two pieces of information do you need to calculate arc length?

Central angle and radius

Step-by-step explanation:

Arc length (A) = (Θ ÷ 360) x (2 x π x r)

What is needed is the angle and radius

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
