Poorly worded question, but I think the answer is A.

[MustKnowHistory]

I get 14 units.

[dinodino]

Sorry, I reread the question and the answer is B.

[immadashell]

B

[kalt]

There’s no way to know for sure without knowing the shape of the blanket. An area of 12 could be 4 by 3, for instance. Then the perimeter (which tells you the length of fabric you need for the border) would be 14. But it could also be 6 by 2 (perimeter 16) or round (perimeter about 12.27) or lots of other things.

B

B....because I quilt.

[ALPAPilot]

That is not a math question, its a question for the lady at the fabric store.

[Leaning Right]

Unless I'm missing something, I think the answer is Not Enough Information Given.

We only know that the area of the blanket is 12 square units. So the blanket could be 6x2, 3x4, 12x1, etc.

Each of those would have a different perimeter, and so would need a different amount of border material.

14

[JudyinCanada]

I get B (14) if the piece is 3x4.

I get 26 if it’s 1x12 and 16 if it’s 2x6.

That’s using the ol’ Perimeter = Length plus width x 2.

[TaMoDee]

B. 3 + 3 + 4 + 4 = 14

[left that other site]

14 units.

Imagine a blanket 3’ x 4’. (12 Sq Ft)

The perimeter is (4 + 3) x 2.

Of course, one would want to allow an extra foot of ribbon to account for hemming, ease, and the mitered corners.

But only a person who sews or quilts would know that.

[Attention Surplus Disorder]

Substitute “feet” for “units”.

The blanket is 12 sq feet.

Could be 3’ x 4’, in which case 3 + 3 + 4 + 4 border = 14 feet.

Could be 6’ x 2’, in which case 6 + 6 + 2 + 2 = 16

Could be 12’ x 1’ in which case 12 + 12 + 1 + 1 = 26 feet.

Could be [sqrt] 12 x [sqrt] 12 = 3.464 x 3.464 in which case (4)(3.464) = 13.85.

Insufficient information to answer unless we assume the blanket is 3 x 4. However, The State wants you to answer 14 feet.

[Rebel_Ace]

The problem as posted lacks sufficient data for a specific answer. Imagine a blanket that is 3 units by 4 units in size, for 12 square units. I would take 3+3+4+4 or 14 units to do a border. Now imagine a blanket 1 unit by 12 units, for 12 square units. It would take 1+1+12+12 or 26 units to do a boader.

Or B. Not sure which.

[mass55th]

I don’t see the answer choice tt Tell Mrs. Feltner to buy a damn baby blanket.

[ClearCase_guy]

The correct answer is:

Rainforests

[Carriage Hill]

If you’re putting a border on both sides, don’t forget to double the answer.
