Answer:
21
Step-by-step explanation:
It is 21 since 21 = 3 * 7.
The other 3 numbers are prime.
Scale 1:2 means that 1 cm on the drawing is 2 cm in reality. So the square is 8cm x 8cm = 64cm².
Notice that while the size gets two times as big, the area gets 2²=4 times as big. That can be confusing. If you actually draw the square on 1:1 and also on 1:2, you can easily see that the latter fits 4 times in the real size...
600/6=100, square root of 100 is 10. your answer is ten.
