A scale drawing of a rectangular park had a scale of 1 cm = 90 m.
5.5 cm
11.5 cm
What is the actual perimeter of the park in meters?

To find the actual perimeter of the park, we need to multiply the measurement on the scale drawing by the conversion factor.

Given a scale of 1 cm = 120 m, the actual perimeter can be calculated by multiplying the measurements on the scale drawing by 120.

For example, if the scale drawing has a length of 10.3 cm, the actual length of the park would be:

10.3 cm * 120 m/cm = 1236 m

Similarly, if the width of the scale drawing is 10.2 cm, the actual width of the park would be:

10.2 cm * 120 m/cm = 1224 m

The perimeter is a sum of all sides, so the actual perimeter of the park would be:

2 * (1236 m + 1224 m) = 2 * 2460 m = 4920 m.

Therefore, the actual perimeter of the park is 4920 meters.

To find the actual perimeter of the park, we need to multiply the measurement on the scale drawing by the conversion factor.

Given a scale of 1 cm = 90 m, the actual perimeter can be calculated by multiplying the measurements on the scale drawing by 90.

For example, if the scale drawing has a length of 5.5 cm, the actual length of the park would be:

5.5 cm * 90 m/cm = 495 m

Similarly, if the width of the scale drawing is 11.5 cm, the actual width of the park would be:

11.5 cm * 90 m/cm = 1035 m

The perimeter is a sum of all sides, so the actual perimeter of the park would be:

2 * (495 m + 1035 m) = 2 * 1530 m = 3060 m.

Therefore, the actual perimeter of the park is 3060 meters.
