Answer:

  $2700

Step-by-step explanation:

Using Heron's formula, we can find the area of the triangle to be ...

  A = √(s(s -a)(s -b)(s -c)) . . . . where s=(a+b+c)/2 and a, b, c are the sides

Here, we have ...

  s = (50 +75 +100)/2 = 225/2 = 112.5

  A = √(112.5 · 62.5 · 37.5 · 12.5) ≈ 1815.461 . . . square yards

Then the profit is expected to be ...

  (1815.451 yd²)($1.50/yd²) = $2723.19 ≈ $2700

The farmer expects a profit of about $2700 from that crop.
