To find the perimeter of the card, we need to first find the length and width. Let's denote the length of the card as L centimeters and the width as W centimeters.
Given that the width is 3 centimeters shorter than the length, we can express the width as W = L - 3.
We also know that the area of a rectangle is given by the formula: Area = length × width. Therefore, we can write the equation for the area of the card as:
L × (L - 3) = 46.75
Expanding and rearranging the equation, we get a quadratic equation:
L^2 - 3L - 46.75 = 0
We can solve this quadratic equation to find the length of the card. Once we find the length, we can substitute it back into the expression for the width to find the width of the card.
After finding the length and width, the perimeter of a rectangle is given by the formula: Perimeter = 2(length + width).
We can substitute the values of length and width into this formula to find the perimeter of the card.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
