Answer

220\text{220}

Step-by-step solution

2 steps

  1. Read the number of buildings for each height range from the histogram.

    • For heights 1-10 meters, there are 40 buildings.
    • For heights 11-20 meters, there are 10 buildings.
    • For heights 21-30 meters, there are 50 buildings.
    • For heights 31-40 meters, there are 10 buildings.
    • For heights 41-50 meters, there are 50 buildings.
    • For heights 51-60 meters, there are 60 buildings.

  2. Sum the number of buildings from all height ranges to find the total.

    Total buildings=40+10+50+10+50+60\text{Total buildings} = 40 + 10 + 50 + 10 + 50 + 60 Total buildings=220\text{Total buildings} = 220

    The total number of buildings is 220\text{220}.
