Answer» Let the sides of a triangular plot is 3x , 5x and 7x 3x + 5x + 7x = 300 m15x = 300x = 300/15 x = 20then the sides of triangular plot is 3x = (3 × 20) = 605x = (5 × 20) = 1007x = (7 × 20) =140now the area of triangular plot is area = √s(s-a)(s-b)(s-c)=√150(150-60)(150-100)(150-140)=1500√3m^2 |
