To explain: an equation in standard form that models all possible combinations of lengths and widths for a rectangle having a perimeter of 100 meters by taking five cases.
Explanation of Solution
Perimeter of the rectangle should be 100 meters.
Now, perimeter of rectangle is given by
Where x and y are the length and width respectively.
Now, for perimeter to be 100, the sum of length and width should be
Now, take some natural numbers whose sum will give 50.
x | 25 | 24 | 23 | 24 | 1 |
y | 25 | 26 | 27 | 26 | 49 |
So, the model equation will be
