Answer:
Step-by-step explanation:
The second and third functions are linear, since both x and y are to the first power.
The first function is cubic and does n ot count here.
The last function seems to involve the square root, and also does not count.
<span>Let us use the variable x for length. So width will be 1/2x + 3.
Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66
Therefore 3x = 66-6 = 60
So x = 60/3 = 20
The length is 20 cm.
Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm
Check: 20+20+13+13 = 66</span>
