let the sides of the triangular plot be 3x , 5x and 7x.
so perimeter is equals to 900m
therefore 3x + 5 x + 7 x = 900
15 x = 900
x = 60
therefore the sides are 180 , 300 and 420.
s=Perimeter/2
=450
area of scalene triangle =√ s x s - A x s minus b x s - c
area=√450×270×150×30
=23,382.68 cm^2
therefore the area is 23382. 68 cm^2
