the scale of a map is 1:20000. Find the length of a road in real life it is 6 cm long on the map
6*20000 = 120000
To find the length of the road in real life, we can use the scale of the map. The scale 1:20000 means that 1 cm on the map represents 20000 cm in real life.
Given that the road is 6 cm long on the map, we can multiply this length by the scale factor to find the length in real life:
Length in real life = Length on the map * Scale factor
Length in real life = 6 cm * 20000 cm
Length in real life = 120000 cm
Therefore, the length of the road in real life is 120000 cm.
To find the length of the road in real life, you can use the scale provided. The scale of the map is stated as 1:20000, which means that one unit on the map represents 20000 units in real life.
In this case, the road is 6 cm long on the map. To find the real-life length of the road, you can set up a proportion:
Map Length / Real Life Length = Map Scale
Let's assign variables to the map length (ML) and the real-life length (RL) of the road:
ML = 6 cm (length on the map)
RL = length of the road in real life (what we want to find)
Now we can set up the proportion:
6 cm / RL = 1 / 20000
To solve for RL, we can cross-multiply:
6 cm * 20000 = RL * 1
RL = (6 cm * 20000) / 1
By multiplying 6 cm by 20000 and dividing by 1, we find that the length of the road in real life is 120,000 cm, or 1,200 meters.
