1. what is the area of this polygon?

2. what is the area of this polygon?

43.5 units²

45.5 units²

46.5 units²

49.5 units²

Part 1) The area of the polygon is

Part 2) The area of the polygon is

Step-by-step explanation:

Part 1) we know that

The area of the figure is equal to the area of rectangle GPST plus the area of triangle PES

Observing the graph

Find the area of rectangle

Find the area of triangle

The area of the figure is equal to

see the attached figure N 1 to better understand the problem

Part 2) we know that

The area of the figure is equal to the area of two triangles  plus the area of a trapezoid

Observing the graph

Find the area of triangle 1

Find the area of triangle 2

Find the area of trapezoid

The area of the figure is equal to

see the attached figure N 2 to better understand the problem

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.
