I’m not sure what you need to round this up to but this is the furthest I got with it. :)
The perimeter is 166.9 ft.
Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)
once you get your answer, convert inches back to feet.
The three decimals that Mrs. Ibara wote were
4.15, 6.30 and 8.45
Now we have to find the other two numbers that are kept blank.
For this purpose, firstly we have to subtract the first 2 decimal numbers and find out the difference.
6.30 - 4.15 = 2.15
Now let us check the difference between the second and the third decimals.
8.45 - 6.30 = 2.15
So the difference is again the same. Then the fourth number will be
8.45 + 2.15 = 10.6
The fifth number will be
10.6 + 2.15 = 12.75
The blank spaces will be 10.6 and 12.75.

Now you combine like terms.
