Answer: The correct answer is A.
Explanation: Age is not a factor in BMI for adults, but it is for children. This is because they are growing. The Centers for Disease Control and Prevention (CDC) use both age and natal sex in its BMI calculations for people between the ages of 2–19 years.
Answer:
36.5 cm²
Explanation:
The perimeter of the smaller shape = 20 cm and The area of the smaller shape = 18.6 cm²
The perimeter of the bigger shape = 28 cm
The length and breadth of the smaller shape is increased by a factor of k to produce the larger shape.
If the length of the smaller shape = l and its width = w. The perimeter of the smaller shape = 2(l + w) = 20
Since The length and breadth of the smaller shape is increased by a factor of k to produce the larger shape, the length of the larger shape = kl and its width = kw. Therefore the perimeter of the larger shape = 2(kl + kw) = 2k (l + w) = 28 cm
To find k, divide the perimeter of the larger shape by the perimeter of the larger shape:
The area of the smaller shape = l * w = 18.6 cm²
The area of the larger shape = kl * kw = k² * l * w = 1.4² * 18.6 cm² = 36.5 cm²
