The area of a square is 32 more than its perimeter. find the length of a side.

The length of a side of the square is 8 unit.

Step-by-step explanation:

Suppose, the length of a side of the square is unit.

Formula for perimeter of square:  

Formula for area of square:  

Given that, the area is 32 more than the perimeter. So, the equation will be......

Moving all terms to the left side, we will get.....

Now, factoring out the left side.......

Using 'zero-product property', we will get......

(Negative value is ignored as the side length can't be in negative)

So, the length of a side of the square is 8 unit.

step-by-step explanation:

maybe try   if it is work from a book, if not try

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
