Question 188311
Perimeter p = 2(l+w) = 300, Dividing by 2 we have  l + w = 150 .......Eq.1
and  l – w = 50 ..................................................... Eq.2
Adding  Eq.1 and Eq.2 we get
2l = 200. , Dividing both sides by 2 we get  l = 100
Since l + w = 150  w = 150 – 100 = 50
The answer is Length = 100 meters and width = 50 meters
