To calculate:The perimeter of the twelfth figure.
Answer to Problem 1E
The perimeter of the twelfth figure is 28.
Explanation of Solution
Given Information: According to the figure 1 the perimeter = 6
For figure 2 = 8 and for the figure 3 = 10
Since, 6,8,10...........n, it asthmatic progressive series, because the common difference are same.
Perimeter = 6 as per figure 1
For figure 2 = 8 and for figure 3 = 10
Since, 6,8,10...........n, this is aAsthmatic progressive series, because the common differences are the same.
