A farmer has a rectangular paddock with Perimeter = 50m and Area =130m2
Perimeter =50m
Area of paddock =130m2
The task is find the dimensions of the paddock.
Here is the formula I created to solve this:
l2−25l+130=0
which, when crunched through the Quad Formula, yeilds:
25±105√2
which in turns yields dimensions of paddock to be length≈17.6m & width≈7.4m
My question: how is it that the exponent on 130m2 can be whisked away like that and still produce a correct answer?
