I dont want to create another thread for this question what if a question states to find the length and width of a rectangle if its area is 48 and perimter is 28. The way i am doing it is that i am ending up with a quadratic equation. Any suggestion.
I end up with the following equation:
l(square) + 48 -14l =0
When applying the quadratic formula i dont get the answer plus i get two values .. there must be an easier and a quicker way of solving this,
