The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
1. 1st transformation is translation the parent function 
6 units to the right to get the function 
2. 2nd transformation is reflection the function 
over the x-axis. This transformation gives you the function 
3. 3rd transformation is vertical stretch of the function 
by a factor of 2 to get the function 
Only last two are present in options, then
answer: C and D.
