Geetha is 13 years old. She weighs 60 kg and is 4 feet and 2 inches tall. What is Geetha’s BMI and weight category?

Answers

Answer;

BMI = 37.20 kg/m²

Weight category ; Obese

Explanation;

  • BMI or the basal metabolic index is calculated by dividing the mass of the body by the square of the body height. It is measured in kg/m².
  • BMI = Body mass/Square of height in meters.

Body mass = 60 Kg

Height in meters = 1.27 meters (converting 4 ft and 2 inch to meters)

BMI = 60÷1.27²

      = 37.20 kg/m²

Therefore; Geetha is obese, since the BMI is above 30 kg/m²

These clouds causes rain (precipitation) which falls on the land and then the water flows back to the ocean.

This cycle is known as water cycle.
