Ratio of sides=2:6:7
Let the sides be 2x, 6x and 7x
Perimeter of triangle=300m
2x+6x+7x=300
x=20m
So, the sides are 40m, 120m and 140m
S e m i p e r i m e t e r equals s equals 300 over 2 equals 150 m
Area of the triangle is
increment equals square root of s open parentheses s minus a close parentheses open parentheses s minus b close parentheses open parentheses s minus c close parentheses end root equals square root of 150 open parentheses 110 close parentheses open parentheses 30 close parentheses open parentheses 10 close parentheses end root equals 900 square root of 55 space m squared
