Answer:

area of rectangle- area of triangle = area of remaining field

now 60 × 50 - area of triangle by herone formula = area of remaining field

↛ Area of rectangular field = length × breadth

= 60 × 50 = 3000msq.

✯ Now, a = 51m, b = 37m, c = 20m

S =  \frac{a + b +  c}{2}

  \frac{51 + 37 + 20}{2}  =   \cancel\frac{108}{2}  = 54m

✯ By Heron's formula :

∴   \sqrt{s(s - a)(s - b)(s - c)}

 \sqrt{54(54 - 51)(54 - 37)(54 - 20)}

 \sqrt{54 \times 3 \times 17 \times 34}

 = 93636m {}^{2}

✯ Hence, the remaining area = Area of rectangle - Area of traingle

→ 3000 - 93636 = 90636msq.

   \boxed {\purple{Remaining  \: area = 90636m {}^{2}}}
