Final answer:
The area of the garden with dimensions of 20 feet by 30 feet is 600 square feet. This can be calculated by multiplying the length and width of the garden plot. A measuring tape would typically be used to obtain these dimensions in real life.
Step-by-step explanation:
The question appears to ask for the area of the garden based on provided dimensions of 20 feet by 30 feet. To find this area, we multiply these dimensions together:
Area = Length × Width
Area = 20 ft × 30 ft = 600 square feet.
The correct answer for the area of the garden, based on the provided dimensions, is 600 square feet, which corresponds to option A.
Regarding measurements, a typical garden plot is longer than just a few feet, and would indeed require a measuring tape to determine the exact dimensions. Answer options B, C, and D are therefore not relevant to the information given in the question.
