on a map with scale 2 cm:25km, what would be the dimensions of a 145 km by 80 km rectangle?

2cm of scale=25km Divide wit25

1km=2/25=0,08cm of scale

145*0,08=11.6cm

80*0,08=6.4 cm

To find the dimensions of a 145 km by 80 km rectangle on a map with a scale of 2 cm:25 km, follow these steps:

Step 1: Determine the scale of the map.
The scale given is 2 cm:25 km. This means that for every 2 cm on the map, it represents 25 km in real life.

Step 2: Calculate the length of the rectangle on the map.
To find the length on the map, divide the actual length (145 km) by the scale factor:
Length on the map = (Actual length / Scale factor) * Map unit length
Length on the map = (145 km / 25 km) * 2 cm
Length on the map = 8.72 cm

Step 3: Calculate the width of the rectangle on the map.
To find the width on the map, divide the actual width (80 km) by the scale factor:
Width on the map = (Actual width / Scale factor) * Map unit length
Width on the map = (80 km / 25 km) * 2 cm
Width on the map = 6.4 cm

Therefore, the dimensions of a 145 km by 80 km rectangle on the map would be approximately 8.72 cm by 6.4 cm.

To find the dimensions of a rectangle on a map with a given scale, you need to convert the real-world dimensions to the corresponding dimensions on the map.

In this case, the scale is given as 2 cm : 25 km. This means that for every 2 cm on the map, it represents a distance of 25 km in the real world.

To find the dimensions of the rectangle, you need to find out how many centimeters on the map represent the given dimensions of 145 km by 80 km.

For the length of 145 km:
Since 2 cm on the map represents 25 km in the real world:
(145 km / 25 km) * 2 cm = 11.6 cm

For the width of 80 km:
Using the same logic:
(80 km / 25 km) * 2 cm = 6.4 cm

Therefore, on the map, the dimensions of the rectangle would be approximately 11.6 cm by 6.4 cm.
