Calculate the BMI
1. Maria Jose's weight is 20 kgs and her height is 110 cm. Get the BMI.

2.Freya's weight is 30 kgs and her height is 142 cm. What is Freya's BMI?

3. Sam's weight is 50 kgs and his height is 163 cm. What is Sam's BMI?​​

Answer 1

1) 16.5.

2) 14.9.

3) 18.8.

Explanation:

First of all, let's refer to the formulas for calculating BMI:

`BMI=(weight(kg))/(height^(2)(m) )=(weight(lb))/(height^(2)(in) )`

Taking into consideration that the weight and height we have are in kg's and cm, let's choose the first formula to simplify the calculations:

`BMI=(weight(kg))/(height^(2)(m) )`

1. Maria Jose's weight is 20 kgs and her height is 110 cm. Get the BMI.

First, we need to convert the hight from cm to m:

`(110cm)/(100) =1.1m`

Calculate BMI:

`BMI=(20(kg))/(1.1^(2)(m) )=(20)/(1.21) =16.5.`

(Rewriting calculations):

20 / (1.1)²=

30 / 1.21 =

16.5.

2.Freya's weight is 30 kgs and her height is 142 cm. What is Freya's BMI?

First, we need to convert the hight from cm to m:

`(142cm)/(100) =1.42m`

Calculate BMI:

`BMI=(30(kg))/(1.42^(2)(m) )=(30)/(2.0164) =14.9.`

(Rewriting calculations):

30 / (1.42)²=

30 / 2.0164 =

14.9.

3. Sam's weight is 50 kgs and his height is 163 cm. What is Sam's BMI?​​

First, we need to convert the hight from cm to m:

`(163cm)/(100) =1.63m`

Calculate BMI:

`BMI=(50(kg))/(1.63^(2)(m) )=(50)/(2.6569) =18.8.`

(Rewriting calculations):

50 / (1.63)²=

50 / 2.6569 =

18.8.
