The question is asking to state how many smaller rectangles are there in an area model that represents 27 time 83, base on my research and calculation, the answer is 4 having the dimensions of 20 by 80, 20 by 3, 7 by 80, 7 by 3. I hope you are satisfied with my answer and feel free to ask for more
Answer ;
4 small rectangles
That is; 20 by 80, 20 by 3, 7 by 80, and 7 by 3.
Explanation;
We have; 27 by 83
We can decompose 27 into 10s and 1s to get; 20 + 7 , and
also decompose, 83 into 10s and 1s to get; 80 + 3;
But we know area is given by length times width, thus;
we have rectangles; 20 × 80, 20 × 3, 7 × 80 and 7 × 3
-The total area will be given by the sum of the area of the four triangles that is equivalent to 83 × 27.
In an area model for 27 × 83 , there are 4 smaller rectangles. Their dimensions are 20 × 80 , 20 × 3 , 7 × 80 , and 7 × 3 . These represent the combination of tens and units from both numbers.
