Here's the question:
The are of a rectangular field is 2275meters squared. The field is enclosed by 200m of fencing. What are the dimensions of the field?
supplose length is x and breadth y
2x + 2y = 200
x + y = 100
xy = 2275
x ( 100 - x) = 2275
x^2 - 100 x + 2275 = 0
Solve this and get value of x
Then from above (x + y = 100) you can get value of y.
