Answer:
- Sides of a triangle are 50 m, 300 m & 300 m
- Area = ?
- We shall use the Heron's Formula for the area but before that we have to find the semi perimeter
- Now we shall find the area of the triangle using the Heron's Formula which is, Area = √{s(s-a)(s-b)(s-c)}

GIVEN:-
The sides of a triangular field are 55 m, 300 m and 300 m.
TO FIND:-
Area of Triangle.
SOLUTION:-
As, the base BASE<<SIDE of a triangle we can assume the height to be approx the side
Therefore,
Height = 300
Area of A = 300*55/2 = 8250
Area of A=(7/15)*(Area of Circle)
8250 (7/15)* π * R*R
R = 75
Perimeter of a Circle = 2*π * R
Therefore,
Ans is 471.4
