The ‘body mass index’ is used to find the body weight that is appropriate for a person’s height. It is calculated using the formula.
I = W/H^2 (I = W divided by H squared)
Where I is the body mass, W is the person’s weight in kg, and H is the person’s height in metres.
Use the formula to find the body mass index for an adult who is 190 cm tall and weighs 75 kg. Give your answer correct to 1 decimal place.

First change the values you have to the units in the formula, cm --> m.
Then substitute the values into the equation and do the processes indicated — square H and then divide it into W to get the value of I.
I hope this helps. Thanks for asking.
To calculate the body mass index (BMI), you will need to convert the height from centimeters (cm) to meters (m). In this case, the person's height is 190 cm. To convert this to meters, divide the height by 100:
Height in meters (H) = 190 cm / 100 = 1.9 meters
Next, substitute the values of the weight (W) and the height (H) into the BMI formula:
I = W / H^2
I = 75 kg / (1.9 m)^2
Now, square the height by multiplying it by itself:
I = 75 kg / 3.61 m^2
Lastly, divide the weight by the squared height to find the BMI:
I = 75 kg / 3.61 = 20.78
To give your answer to one decimal place, round the BMI to the nearest tenth:
BMI = 20.8
Therefore, the body mass index (BMI) for an adult with a height of 190 cm and weight of 75 kg is 20.8.
