Final answer:
The equation x² + 2x + 1 = 151 can represent finding the dimensions of a rectangular garden.
Step-by-step explanation:
A real-life situation that could be represented by the equation x² + 2x + 1 = 151 is finding the dimensions of a rectangular garden. Let's say that the length of the garden is represented by 'x'.
garden can be represented by 'x + 1'. The equation can be used to find the value of 'x' that satisfies the condition that the area of the garden is equal to 151 square units.
