mr. ming may swim the perimeter of Pool A or Pool B. In which pool must he swim farther? How much farther? Pool A measurements: 10m, 2m Pool B: 7m, 7,
Pa = 2(10) + 2(2) = ?
Pb = 2(7) + 2(7) = ?
To determine in which pool Mr. Ming must swim farther, we need to compare the perimeters of Pool A and Pool B.
The perimeter of a rectangle (such as a pool) is calculated by adding the lengths of all its sides. In this case, Pool A has sides of 10m and 2m, while Pool B has sides of 7m and 7m.
To find the perimeter of Pool A:
Perimeter of Pool A = 2 * (length + width)
Perimeter of Pool A = 2 * (10m + 2m)
Perimeter of Pool A = 2 * 12m
Perimeter of Pool A = 24m
To find the perimeter of Pool B:
Perimeter of Pool B = 2 * (length + width)
Perimeter of Pool B = 2 * (7m + 7m)
Perimeter of Pool B = 2 * 14m
Perimeter of Pool B = 28m
Comparing the two perimeters, we can see that Mr. Ming must swim farther in Pool B. The difference in distance is equal to the difference in perimeters:
Difference in distance = Perimeter of Pool B - Perimeter of Pool A
Difference in distance = 28m - 24m
Difference in distance = 4m
Therefore, Mr. Ming must swim 4 meters farther in Pool B compared to Pool A.
