Question 1:

Define scale. What are the different types of scales? Mention their advantages and

disadvantages.

Question 2:

A surveying map was drawn with scale 1:100. The distance between two points A and B

was measured on the map and was 19.6cm. What is the real distance between the two

points? If the line AB represents a border of a rectangular residential building with width

13.7m. Calculate the area of the building in real and on the map.

Question 3:

Using an old map to get the area of a triangular area, the lengths of the three borders

were 17.06 cm, 13.6 cm and 21.3 cm. measuring only the first side of the area in the

field and was 170.60m, calculate:-

a-The area on the map

b-The used scale

c-The true area

Question 4:

The length of a line was measured on a map and found to be 5cm. If the actual lengthof this line is 250m, determine the scale of the map. After that, the area of a circular

building was obtained from the same map and found to be 28.27cm2. Calculate the

actual real area of this building in m2.

Question 5:

Design a graphical scale 1:1000 with accuracy 0.50m. Show a length of 24.5m on this

scale.

Question 6:

Design a graphical scale 1:5000 with accuracy 2m. Show a length of 19m on this scale.

Question 7:

Design a graphical scale 1:2500 with accuracy 1m. Show a length of 116m on this scale.

Question 8:

Design a graphical scale 1:100 with accuracy 0.2m. Show a length of 2.4m on this scale.
