Never

Step-by-step explanation:

The product of (a − b)(a − b) is solved using the perfect square trinomial formula. This formula (for subtraction) states that (a − b)^2 = a^2 - 2ab + b^2.

a^2 - 2ab + b^2 is NOT equal to a^2 − b^2.

So, the product of (a − b)(a − b) is NEVER a2 − b2

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
