1 is the least prime number
Hello!
Multiply:
21.33 × 2.04 = 43.5132
Add:
1.115 + 3.18 + 22.0613 + 12.2384 = 38.5947
Subtract:
43.5132 - 38.5947 = 4.9185
Answer:
Alex can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number
Step-by-step explanation:
We are told that Alex is drawing rectangles with different areas on a centimeter grid, and he can draw 3 different rectangles with an area of 12 cm²
We have the minimum grid length of centimeters = 1 cm, since we assume that only integers can be used.
That is to say:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
These are the 3 different rectangles with an area of 12 cm²
Now we have to find how many rectangles Alex could draw with an area of 11 cm²
11 = 1 x 11
Therefore, only one factorization is possible. Which means that you can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number, which means only the common factor of 1 and the number itself, that is, 11.
Brainstorming is a problem solving technique that attempts to come up with as many solutions as possible in a short time without censoring the ideas.
