the area of sq is 1024
1)find its each side
2)find its perimeter
3)find the time taken by a man to make 5 rounds of the feild walking at the speed of 4.5 km/h
The square root of 1024 = 32
P = 4S
32 = 4S
S = 8
3)
(32 * 5 * 4.5) / 1000 = ________km/h

To answer the questions, we need to use the given information and apply relevant formulas. Let's break down each question:
1) Finding the side of the square:
The formula to calculate the area of a square is A = s^2, where A is the area and s is the length of one side. In this case, we know that the area is 1024. Thus, we can rewrite the formula as 1024 = s^2. To find the side length (s), we need to take the square root of both sides: s = √1024. Evaluating the square root, we find s = 32. Therefore, each side of the square is 32 units long.
2) Finding the perimeter of the square:
The formula to calculate the perimeter of a square is P = 4s, where P is the perimeter and s is the length of one side. Since we found the side length to be 32 units, we can substitute this value into the formula: P = 4 * 32. Evaluating the expression, we get P = 128. Therefore, the perimeter of the square is 128 units.
3) Finding the time taken to make 5 rounds of the field:
To find the time taken, we need to determine the distance travelled for 5 rounds and divide it by the speed. If we assume that each round covers the perimeter of the square, then the total distance covered in 5 rounds is 5 * (perimeter of the square). Since we already know the perimeter is 128 units, the total distance becomes 5 * 128 = 640 units.
Further, if we know the speed of the person is 4.5 km/h, we need to convert the distance from units to kilometers. If we do not know the unit of the given distance, we cannot provide a specific answer. Please provide the appropriate unit for the distance so we can proceed with the calculation.
