"the argument" of a function, is simply "the expression being evaluated by that function".
Multiply 370 by 0.16 get get 16%
370 x 0.16 = 59.2%
The answer is 30.
You need to use sine here
So:
Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
The length is 12 + 10 = 22 yards.
