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.
The length and breadth of a rectangle are a factor pair of the area of the rectangle.
One to one. Each factor pair represents a rectangle.
12 has three factor pairs, six if you count their negative counterparts.
Divide by 5. (65,1)(13,5)
yes
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.
Explaining how to find all factors pairs of 40 is easy. All you have to do is find which whole numbers 40 can be divided into.
The dimensions for area are [L2]
length times width
27:55
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
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
PUT A HAT On it
To calculate the volume of a rectangle, you must multiply the length, the width, and the height--so the volume depends on the dimensions.
