Answer:
Part A) The area of the figure is 
Part B) The perimeter of the figure is 
Step-by-step explanation:
step 1
Find the area of the figure
we know that
The area of the figure is equal to the area of triangle ABD plus the area of triangle BCD
The area of triangle is equal to

<u>Area of triangle ABD</u>
Observing the graph


substitute

<u>Area of triangle BCD</u>
Observing the graph


substitute

The area of the figure is

step 2
Find the perimeter of the figure
we know that
The perimeter of the figure is equal to

we have

the formula to calculate the distance between two points is equal to
Find the distance AB
Find the distance BC
Find the distance CD
Find the distance AD
substitute the values

Subtract 89 from -42. k=-131
The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
<h3>How to determine the correlation coefficient</h3>
The formula of correlation coefficient is:

Using the dataset from the complete question, we have:

Evaluate the difference

Evaluate the quotient

Approximate

Hence, the correlation coefficient is 0.234
