That number would be 6.
Since 5^2 = 25 and 6^2 = 36, we can see that the only possible whole number between sqrt(27) and sqrt(39) has to be 6.
Just like you drew those dotted lines. You know how to find the areas of rectangles which is A=length x width
The answer would be 20cm^2+6cm^2+18cm^2=44 cm^2
Answer:
-11/10 or -1 1/10
Step-by-step explanation:
Change to improper fractions format
1 6/10 becomes 16/10
2 7/10 becomes 27/10
16/10 - 27/10 = -11/10
-11/10 is also written -1 1/10
