Given information
- A farmer with 750 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle.
Step-by-step explanation
Step 1.
A farmer with 750 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle.
If width is then then the total remaining length of fence will be
Since we have to divide area into four pens parallel to length of rectangle, we get 5 parallel side.
Length of those 5 parallel side will be .
So choosing different widths of rectangle, we can find its different lengths.
