Not sure what it means by "classify" But I'm assuming it just means name the shapes. If that's the case,
11 is a square, because all the inside lines are the same length, and all meet at 90 degree angles.
12 is a rectangle, because all the sides are parallel, but they are not congruent.
13, I've no idea.
I sincerely hope I helped, though I probably did not.

Answer:

Step-by-step explanation:

<h3>
Answers: C) 4.5 m, D) 3.92 m, E) 3.5 m</h3>
Work Shown:
Convert from feet to meters.
15 feet = (15 ft)*(0.3048 m/1 ft)
15 feet = (15*0.3048) meters
15 feet = 4.572 meters approximately
From this point onward, we select all answer choices that are less than 4.572 meters. Those would be C, D and E.
If you have 20% of an number you simply divide it by 5.
So if you divide a number by 5 and find eleven, it should look like:
x / 5 = 11
So it means x = 55
Hope this helps. :) Don't forget to choose brainliest answer please.
