4 pounds is the correct answer.
explanation:
the baby gained 4 lbs during the first 4 months. then the baby gained 3 during the second 4 months. that is a total of 7. subtract that from 11, and you have 4 lbs.
The formula for the perimeter is 2L + 2W.
Since we know that L=10+W, we can substitute this into the equation.
2(10+W) +2W=124
20+2W + 2W=124
4W +20 = 124
4W=104
W=26
Therefore, the width is 26 inches.
7 * 4 = 28
28 + 5 = 33
33 / 3 = 11
11 - 7 = 4
