Write a C program to input length and width of a rectangle and find area of the given rectangle. How to calculate area of a rectangle whose length and breadth are given by user in C programming. Logic to find area of a rectangle whose length and width are given in C programming.

**Example**

**Input**

Input length: 5 Input width: 10

**Output**

Area of rectangle = 50 sq. units

## Required knowledge

Fundamentals of C, Data types, Talking user input in C

## Area of rectangle

Area of rectangle is given by the formula -

Where l is length and w is width of the rectangle.## Logic to find area of rectangle

Logic to calculate area of a rectangle is almost similar to the previous program (perimeter of rectangle). We only need to apply a different formula. Below is the step by step descriptive logic to find area of rectangle -

- Read length and width of rectangle and store it in two different variables say length and width.
- Apply the formula to compute area area = length * width.
- Print the resultant area.

## Program to find area of rectangle

/** * C program to find area of rectangle */ #include <stdio.h> int main() { float length, width, area; /* * Input length and width of rectangle */ printf("Enter length of rectangle: "); scanf("%f", &length); printf("Enter width of rectangle: "); scanf("%d", &width); /* Calculate area of rectangle */ area = length * width; /* Print area of rectangle */ printf("Area of rectangle = %f sq. units ", area); return 0; }

Enter length of rectangle: 5 Enter width of rectangle: 10 Area of rectangle = 50.000000 sq. units

Happy coding ;)
