are two ways to find a missing length of proportiontain proportion, the diagram may be longer or smaller than the actual object.

Example One: Use scale to determine the Actual Length of an Object.

For a scale of 1:14 and a

diagram measuring 5.5c

m set the proportion.

SCALE: is a comparison

of two objects; the actual size and its diagram.

Scale can be expressed as a ratio, as a fraction, as a percent, in words or as a diagram.

A scale of 1:50 means that 1 unit on the diagram is equal to 50 units of the actual object.

**SCALE DIAGRAM :**Is similar or the actual or

object. It maintain proportion, the diagram may

be longer or smaller than the actual object.

There are two ways to find a missing length of proportion

Becau

se it is easy to find the relationship of 1 to 5.5 it easy to find x, simply multiply 14 by 5.5 to find x=77cm- So the actual object is 77cm.

Example Two: Use Measurement to find Scale.
