Slide 1: Introduction

Welcome to the BMI Calculator App presentation.

This app helps users determine their Body Mass Index based on their height and weight inputs.

Slide 2: App Features

• Accepts user input: Height (cm) and Weight (kg)
• Calculates BMI reactively
• Displays a message indicating health status:
  • Underweight
  • Normal
  • Overweight
  • Obese

Slide 3: How It Works

Formula Used:

\[ BMI = \frac{weight(kg)}{(height(m))^2} \]

The app uses this formula inside a reactive function to update results in real-time as the user inputs change.

Slide 4: Sample Calculation (R code)

height_cm <- 170
weight_kg <- 65
height_m <- height_cm / 100
bmi <- weight_kg / (height_m ^ 2)
bmi

## [1] 22.49135

This calculates BMI for a person who is 170 cm tall and weighs 65 kg.
