David wants to build a pen for his goat. He wants the area of the pen to be 48 square feet. If the length and width of the pen are whole numbers, which of the following could be the perimeter of the pen?

- p = 26 ft
- p = 28 ft
- p = 30 ft
- p = 36 ft

1. P = 22 ft
2. P = 28 ft
3. 6 ft
4. 10 ft
5. A = 80 cm 2
6. 10.5 in.
7. 53 in.
8. P = 24 ft
9. A = 36 ft 2
10. One side of a square equals 2 feet
11. The windows have the same area: The perimeter of Window B is 20 feet
12. The area for the square is 16 square inches: The area of the square is equal to the perimeter of the square.
100% correct your welcome good luck

The factors of 48 that multiply to give 48 are 2 *24, 3*16, 4*12, 6*8

Solving from the options
Perimeter = 2L +2B
Starting with 6 and 8 we have
2(8)+2(6)= 16+12= 28
That's the answer....

If the area is 48 square ft., the length would be 16 ft., and the width would be 3 ft. Correct?

Oh god, I'm so stupid, they would all equal 48! HAHA!! Oops.

8 times 2 is 16, plus 6. That would equal 22, so it would have to be 4 and 12. 12 times 2, plus 4. 24 plus 4 equals 28, which is an answer choice. Thanks Ms. Sue!

P = 2L + 2W

P = 32 + 6
P = 38

But that's not one of your answer choices.

Try again.

A = L times W, right? 3 times 16 is 48. I am confused.

What are the factors of 48?

2 and 24, 3 and 16, 4 and 12, 6 and 8.

Yep! Now which one of those pairs fits one of your perimeter answer choices?
