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.
3 lip 2023 · STEP 1. Use a ruler to measure the distance accurately on the map. For example, measuring a length from A to B as 5.8 cm. STEP 2. Use the scale to find the actual distance in the same units (usually cm) For example, if the scale is 1 : 150000 the actual distance = 5.8 cm × 150000. STEP 3. Convert the actual distance to a more suitable unit.
How to write scales as ratios, and use them to find measurements for scale drawings and real lengths with BBC Bitesize Maths. For children between 11 and 14.
A map scale is given as 1 cm = 2 km. This means that every cm on the map represents 2 km in real life. Example. The distance between two towns on a map is 8 cm.
A scale drawing is created by multiplying each length by a scale factor to make it larger (an enlargement) or smaller (a reduction) than the original object. The scale of a drawing is usually stated as a ratio. For example, 1 \, cm \, \text{:} \, 5 \, m.
