Read each example of data below and identify whether it is qualitative or quantitative. 28.5 cm tall rough-textured the bird bobbed its head up and down.

Step-by-step explanation:

Quantitative data include measure of value that are expressed in numbers. For example, 365 days in a year, 24 hours in a day, 7 continents of the world etc.  

Qualitative data is non-numerical data. This includes characteristics (color, texture and taste), symbols and description. Its subjective and cannot be measured.  

The statement in the question has both qualitative and quantitative data.  

An easy way to differentiate between the two is to find whether the data is expressed in numbers. If numerical are involved e.g. mass of 78 pounds, 250 ml of water, force of 10N etc., then the data is quantitative. If it can’t be counted or measured, then its qualitative.  

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
