1.	Side of triangle 3:5:7,perimeter=300,find it\'s area
Answer» Ans,x =20 and area =1500√3m square Let the sides of a triangular plot is 3x , 5x and 7x3x + 5x + 7x = 300 m15x = 300x = 300/15x = 20then the sides of triangular plot is3x = (3 × 20) = 605x = (5 × 20) = 1007x = (7 × 20) =140now the area of triangular plot isarea =\xa0\xa0
