I think you are thinking of using the rectangles like you use Punnet squares. One side is multiplied times the other side and the product is put in the inside squares. This is handy when trying to factor expressions that are polynomials.
No, you should continue checking for factor pairs even if you find a pair that repeats. A repeating pair indicates that the number is not a prime number, but there may be other factor pairs that have not been identified yet. It is important to exhaust all possible factor pairs to ensure that all factors of the number are identified accurately.
12 has three factor pairs, six if you count their negative counterparts.
Divide by 5. (65,1)(13,5)

I am not sure what you mean with "area models". As for an array, one simple way to use it is to try out different factors in a loop; every time you find a factor, you write the factor to the next array element.
The dimensions for area are [L2]
Ah, what a lovely question! To find the perimeter of a rectangle, we need to know both the length and width. Since the area is 432 square feet, we can find the dimensions by factoring 432 into pairs of numbers until we find a pair that could be the length and width of the rectangle. Once we have the dimensions, we can simply add up all the sides to find the perimeter.

You can't tell the dimensions of a rectangle from its area, or the dimensions of a prism from its volume.
Find the dimensions of the rectangle of largest area that can be inscribed in a circle of radius a in C programming
The new dimensions are 4cm and 7cm
a rectangle has a perimeter of 72m. If the length is 20 m longer than the width find its dimensions?
84 factor is
PUT A HAT On it
The dimensions are W and W+M where W is the width.
The dimensions are 10 m by 6.5 m and so 10*6.5 = 65 square m
