Answer:
Blue = 116 m^2
Step-by-step explanation:
The area of the path and the square = 30*30 = 900 m^2
The size of the square = 30 - 2 = 28. The square = 28^2 = 784
The path takes up the difference between the two 900 - 784 = 116
I think it is 47 not sure
Answer:
39
Step-by-step explanation:
Formula for the nth term (an) = a1 + d(n - 1) where a1 = the first term and d = common difference.
So here the 13th term = 3 + 3(13 - 1)
= 3 + 3*12
= 39 (answer).
