My daughter has this problem-solving question for her homework. I'm feeling kind of dumb on this one. What do you think is the correct answer?

Mrs. Feltner wants to put a border on a baby blanket. The area of the blanket is 12 square units. Which shows how many units of materials she needs for the border?

A 12 units B 14 units C 15 units D 21 units

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

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.

if the blanket is 3x4 it would be 14, three for each of the shorter sides and 4 each for the longer sides. 2x6 and 1x12 would be the same

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

2 border units for each of the 4 corner units, 1 border unit each for the other 8 units.

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.

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.

Why would 2x6 by the same? Wouldn’t it be 16 instead of 14? And 1x12 would be 26.

B. 3 + 3 + 4 + 4 = 14

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.

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.
