Step-by-step explanation:

We can solve the given system by making the equations equal becase .

The equations are and , which forms

Using this value, we find the other one.

Therefore, the solution of the system is

$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
