Answer:

Step-by-step explanation:
we have

Applying property of exponents


It's 11 because 6+5=11 other words it means it's 11 squares away
P = 2(L + W)
P = 128
L = 2W + 4
128 = 2(2W + 4 + W)
128 = 2(3W + 4)
128 = 6W + 8
128 - 8 = 6W
120 = 6W
120/6 = W
20 = W <=== width is 20 ft
L = 2W + 4
L = 2(20) + 4
L = 40 + 4
L = 44 <=== length is 44 ft
So,

Write in prime factored form.

Cross-cancel
The period of a sinusoid

is

, so any range such that

will give two complete periods.
