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

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.

any1 help..how do i work this out?

Is it (w/h)^2 where you square the whole fraction, or just squaring h? plz clear this up

its I = W divided by H squared
