Ms. Newton's flower bed is shaped like a triangle as shown. Find the area of the flower bed in square
feet. If one bag of topsoil covers 10 square feet, how many bags are needed to
cover this flower bed?
b=4
h=2

3 bags are needed to cover this flower bed

Step-by-step explanation:

Use conversion:

1 yard = 3 feet

Area of a triangle(A) is given by:

where,

b is the base and h is the height of the triangle.

As per the statement:

From the given diagram:

Base(b) = 3 yards = 9 feet

Height(h) = 2 yard = 6 feet

then;

square feet.

Since, it is given that if one bag of topsoil covers 10 square feet

⇒10 square feet =  1 bag

then\;

in 27 square feet =  bag

Therefore, 3 bags are needed to cover this flower bed

Step-by-step explanation:

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.
