The scale 1 : 12∙5 is a unitary ratio in the form 1 : n. 1 cm on the scale drawing represents 12∙5 cm in real life. The drawn length multiplied by 12∙5 gives the real length.
Scale Drawings. The lengths in a scale drawing are in proportion to the actual lengths of an object. We often use a ratio to show the scale of a drawing. If we have a scale of 1:5 all of the lengths in the scale drawing are 5 times smaller than in real life.
The scale of a drawing is usually stated as a ratio. For example, 1 \, cm \, \text{:} \, 5 \, m. You would read this as “ 1 centimeter to 5 meters” which means that every 1 centimeter on the diagram represents 5 meters in real life.
The scale of a drawing is usually stated as a ratio. E.g. 1cm:5m . This is said as “ 1 centimetres to 5 metres” and means every 1 centimetre on the diagram represents 5 metres in real life. In order to interpret and produce scale drawings we need to know the scale factor and the actual lengths of the object. E.g.
Scale drawings, map scale, map distance, actual distance, writing a scale in ratio form, simplifying a scale, calculating the actual distance using a scale and calculating the scaled distance using the actual distance.
Scale maths is used for real world scale drawings as it is much easier to create a scale drawing of an object, than to draw the object using actual distances. The ratio usually takes the form 1: n1: n of the model/plan to the actual distance.
Key points. A. map scale. is a ratio of the distance on a map to the actual distance on the ground. The. scale. of a map shows how much you need to enlarge the map to get the actual size. For...
