Final answer:
To calculate the perimeter of a four-sided plot like ABCD, all four sides' lengths must be summed. The question provided is missing specific side lengths, making it impossible to determine an answer. Normally, the formula P = 2l + 2w is used for rectangles to find the perimeter.
Step-by-step explanation:
To find the perimeter of a four-sided figure like ABCD, you need to add the lengths of all four sides together. However, in the question provided, it's not clear what the lengths of the sides are, as there is no accompanying figure or specific side lengths given in the information provided. Normally, if you have a rectangle, for example, the perimeter formula is P = 2l + 2w, where l is the length and w is the width.
In one of the referenced questions, the perimeter of a town square is calculated as 'P = 2l + 2w,' which would imply that the square has two sides of equal length (l), and two sides of equal width (w). For a town square with a length of 39.2 meters and a width of 17.5 meters, the calculation would be P = 2(39.2) + 2(17.5) = 78.4 + 35 = 113.4 meters.
Given the information in question 20, we can't calculate the perimeter of ABCD without additional data. It's essential to have the lengths of all sides to proceed with an accurate calculation. Since the question refers to an estimate to two decimal places, if we knew the individual side lengths, we would sum them up and round to two decimal places to get the perimeter.
