# C Exercises: Compute the perimeter and area of a rectangle

## C Basic Declarations and Expressions: Exercise-5 with Solution

Write a C program to compute the perimeter and area of a rectangle with a height of 7 inches. and width of 5 inches.

C programming: Perimeter of a rectangle

A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek peri (around) and meter (measure). The perimeter can be used to calculate the length of fence required to surround a yard or garden. For rectangles or kites which have only two different side lengths, say x and y, the perimeter is equal to 2x + 2y

C programming: Area of a rectangle

The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size, square units of measure are square inches, square centimeters, or square miles etc. The formula for the area of a rectangle uses multiplication: length • width = area.  A rectangle with four sides of equal length is a square.

C Code:

``````#include <stdio.h>
/* height and width of a rectangle in inches */
int width;
int height;

int area;
int perimeter;

int main() {
height = 7;
width = 5;

perimeter = 2*(height + width);
printf("Perimeter of the rectangle = %d inches\n", perimeter);

area = height * width;
printf("Area of the rectangle = %d square inches\n", area);

return(0);
}
``````

Sample Output:

```Perimeter of the rectangle = 24 inches
Area of the rectangle = 35 square inches
```

## Solution

```#include <stdio.h>
/* height and width of a rectangle in inches */
int width;
int height;

int area;
int perimeter;

int main() {
height = 7;
width = 5;

perimeter = 2*(height + width);
printf("Perimeter of the rectangle = %d inches\n", perimeter);

area = height * width;
printf("Area of the rectangle = %d square inches\n", area);

return(0);
}```
