In a diagram of a landscape plan, the scale is 1 cm = 10 ft. In the diagram, the trees are 4.7 cm apart. How far should the actual trees be planted?
If the scale is 1 cm = 10 ft, then we need to convert 4.7 cm to feet to find out how far apart the actual trees should be planted.
1 cm = 10 ft
So,
4.7 cm = 4.7 x 10 ft/cm = 47 ft
Therefore, the actual trees should be planted 47 feet apart.
