By definition, the area of a rectangle is given by:

Where,
w: width
l: long
We then have the following area:

Factoring the area we have:

Therefore, according to the definition, two possible dimensions of the rectangle are:
Answer:
The area of the rectangle in factored form is:
One possible set of dimensions for this rectangle is:
Answer:
chisquare = 31.667
degree of freedom = 2
Step-by-step explanation:
Formula for chisquare test = (O-E)²/E
total number observations= 60 + 25 + 15 = 100
Estimated E,
80% x 100 = 80
15%x100 = 15
5% x 100 = 5
chisquare =

= 5 + 6.67 + 20
= 31.667
from the calculation above the value of the chisquare statistic = 31.67
the degree of freedom is the number of samples in the test n - 1
= 3-1
= 2
I have solve this question also in a tabular form to aid understanding in the file i uploaded.
thank you and good luck!
the yellow one is correct, I did the math. I am 99% sure this is correct, but I would love it if you privately texted me if this is not the answer.
Thank you
Good luck
