Answer 1

BMI - Body mass index

= weight in kg /height in m2

Adel -

• BMI when 22 years old,

Weight = 240 lbs = 108 kg

Height = 185 cm = 1.85m

BMI = 108 /(1.85) 2

  = 31.5

• BMI when 24 years old

Weight = 90kg

Height =1.85 m

BMI =90/1.852

  = 26.3

BMI more than 25 and below 30. So it is overweight. Not healthy range.

Tamini

• At 18 yeara old

Weight =8stone 6 pound = 53.52 kg

(1 pound =0.45kg 1 stone = 6.35 kg)

Height = 162cm =1.62m

BMI = 20.42

• At 19 years old

Weight =99Ibs = 44.9 kg

Height =1.62m

BMI =17.14

BMI becomes less than 18.5 - - > underweight.

**Normal value of BMI:-

Underweight = <18.5

Normal weight = 18.5–24.9

Overweight = 25–29.9

Obesity = 30 or more
