Answer 1

Now the question has described the formula of Body Mass Index (BMI) as:

BMI
`=(w)/(h^2) * 703`

Where 'w' is weight in pounds and 'h' is the height of the person in inches.

We need to find the weight of a 13 year old boy whose height is 60 inches and the BMI value of his body is 20.5.

Now, we have
`h=60`,
`BMI=20.5`

Plugging the values in the formula of BMI we get:

`20.5=(w)/((60)^2)* 703`

Solving for 'w' we get:

`w=(20.5* (60)^2)/(703) =104.97\approx105`

Hence, the weight of 13 year old boy is 105 pounds.
