Depends whether the blanket is three units by four units, in which case the answer is fourteen units, or if it’s a long bed and the blanket is six units by two units, the answer is sixteen units - or if it’s a real long bed and the blanket is twelve units by one unit, the answer is twenty-six units, or if....I think you need a new math teacher.....

12 units sq^2 is 3x4. If the sides with four units have their sides covered, than it would be the two middle square units, on the sides that need covering.

4+4+1+1= 10 units needing covering. :)

You have to know the length and width to answer the question.

I guess the question is to confuse students about math, to force them to rely on authority for ‘context’ or ‘narrative’ in order to get an answer. It’s not really a math question.

if the AREA is 12sq ft then it must be a 3x4 ft blanket

3+4 times 2 = 14

(two 3 ft sides and two 4 ft sides)

The “only available correct answer” is B (14). There are other possible correct answers but they are not available. A child taking “old fashioned math” would probably easily figure it out; however, those of the “new math” and “common core” schools will be struggling and guessing forever.

It’s B but only if the blanket is 3 units by 4 units. Otherwise, there’s no way to tell. A blanket 1 unit wide by 12 units long will have a border of 26 units but still has an area of 12 square units.

How big is the border supposed to be? Is it 1 inch or 1 foot? I don’t know how to sew.

The only possible answer is B, none of the other answers could possibly be correct.

1. Is this Common Core?
2. If answer to #1 is yes, the answer to the question is patriarchy.

Not enough information.

This is not a geometry question. It is union made.

The answer is “Borders are racist.”

According to Common Core, first you have to make friends with the ten in the twelve. Then you have to add another friend to make twenty. From the twenty, you have to add the one and the two from the twelve to make twenty-three. Now, two plus three is five, which you add to the original twelve to get seventeen. But since you added three numbers together, you take back three from seventeen to get fourteen, and there’s your answer: B.

14 units

It is 12 square units, therefore, 3units up top, 3 units on the bottom, 4 units to the left, and 4 units to the right.

Does the diagram below help?

Assuming whole units and a rectangular shape it must be an even number, and therefore B is the only available choice.

What grade is this for?

Insufficient information. This is just the kind of problem that a teacher with no grounding in math will give to a student, then look in the key to answer.
