Question

construct a linear scale to show 2 kms mark on primary division and 200 m mark on the secondary division when the R.F is 1:60000​

Answer 1

Answer:

Representing scales: The proportion between the drawing and the map can be represented by two ways as follows:

a) Scale: – 1cm ≡ 1m or 1cm ≡ 100cm or 1:100

b) Representative Fraction: – (RF) 1/100 is the ratio between the size of the drawing and the object.

Table: Metric Units Table: FPS Units

1 Kilometre (km) =10 Hecta metres (hm) 1 Mile =8 Furlongs

1 Hectametere(hm) =10 Decametres(dam)or 0.1km 1 Furlong =220 Yards

1 Decametre(dam) =10 Metres (m) or 0.1hm 1Yard =3 Feet

1 Metre(m) =10Decimetres(dm) or 0.1dam 1 Feet =12 Inches

1 Decimetre(dm) =10 Centimetres(cm) or 0.1m

1 Centimetre(cm) =10 Millimetres (mm) or 0.1dm
