Step-by-step explanation:
First of all, let's refer to the formulas for calculating BMI:
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:
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:
Calculate BMI:
(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:
Calculate BMI:
(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:
Calculate BMI:
(Rewriting calculations):
50 / (1.63)²=
50 / 2.6569 =
18.8.
