Scales

The document outlines various tasks related to constructing different types of scales, including diagonal and vernier scales, with specific measurements and representations. It includes instructions for scales with different ratios, such as 1:5, 1:50, and RF = 1/80, and specifies distances to be marked on these scales. The tasks involve converting measurements from a map to real-world distances and vice versa.

Sheet No: 3 SCALES

1. Construct a scale of 1:5 to show decimetres and centimetres and to read upto 1
metre. Show the lengths of 7.6 dm and 48 cm on it.

2. An area of 144 sq cm on a map represents an area of 36 sq km on the field. Find the


RF of the scale for this map and draw a diagonal scale to show kilometres,
hectametres and decametres and to measure upto 10 kilometres. Indicate the
following distances on the scale a) 5.36 km b) 73 hectametres.

3. Draw a full size vernier scale to read and lengths and mark on it lengths of
! !"
!" !"" !""
5 !" , 2 !"  and !" .

4. Draw a scale of 1:50 showing metres and decimeters, and to measure upto 8
metres. Show the lengths of 740 cm and 32 dm.

5. The distance between two points on a map is 5.75 inch. The points are actually 20
miles apart. Construct a diagonal scale of the map, showing miles and furlongs and to
read upto 25 miles.

6. On a building plan, a line 20 cm long represents a distance of 10 m. Devise a


vernier scale for the plan to read upto12 m. Show on your scale the lengths 65.8dm
and 9.14 m.

7. Construct a diagonal scale of RF = 1/80 to read inches and to measure upto 15


yards. Mark 4 yd 1 ft 9 in, 6 yd 2 ft 3 in and 2 ft 7 in.

8. Construct a vernier scale of RF = 1/32 showing yards, feet and inches and measure
upto 4 yards.
