I'm confused and not sure if I'm correct. Please Help

The correct answer is b.

Explanation

In the image you can see a staff with a treble clef, this means that the fourth line from top to bottom is in the key G. According to this, the first note that is in the first place on the staff is the note E, then the correct option would be to say that in a guitar tablature the first string must be played without pressing any fret since this string is tuned to the note E. The second note of the staff is two tones above the M, so would be to be a G note, which would be the same as playing the first string pressed on the third fret, which would give a G note. Finally, the third note shown on the staff is D, which on a guitar would be played by playing the second string at the third fret. Based on the above, the correct answer is B.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172
