So every 2cm equals 7m in real life. If the slide is 6cm long, then the real slide is 21m. How? Well think about it, 2cm goes into 6cm 3 times, and if you look at the scale it will be 7+7+7 giving you 21m.
First, you have to understand that 2cm on the map represents 7m on the actual ground.
Since the slide in the map measures 6cm, (6 X 350)cm = 2100cm
Thanks a lot .Greate help
