Question

Do you have a large swimming pool? If you were to walk around a particularly large pool, you would walk 1110 meters. If the pool is 420 meters long, how wide is the pool? (Assume the swimming pool is a rectangle.)

Answer 1

The width of the large rectangular swimming pool is 135 meters, calculated using the perimeter formula for a rectangle: P = 2×(l + w), with a given perimeter of 1110 meters and length of 420 meters.

Step-by-step explanation:

The student's question about the swimming pool is related to perimeter and area calculations, which is a topic within Mathematics. To find the width of the rectangular pool, we need to use the perimeter formula for a rectangle which is P = 2×(l + w), where P is the perimeter, l is the length, and w is the width. Given that the perimeter is 1110 meters and the length (l) is 420 meters, we can substitute these values into the formula and solve for the width (w):

1110 = 2×(420 + w)
555 = 420 + w
w = 555 - 420
w = 135 meters

So the width of the large swimming pool is 135 meters.
