The perimeter is the path around the two-dimensional shape. Perimeter can be used to calculate the length of fence needed to enclose a yard or garden. For a rectangle with only two sides, say x and y, the perimeter is equal to 2x 2y.

The formula for the area of ​​a rectangle uses multiplication: length x width = area. A rectangle with four equal sides is a square. The units of rectangular area are square meters, square centimeters, etc.

c language calculates the perimeter and area of ​​a rectangle

The code example is as follows:

#include <stdio.h> 
/* 长方形的高和宽,单位为米*/
int width;          
int height;         

int area;           
int perimeter;      

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

    perimeter = 2*(height + width);
	printf("矩形的周长 = %d 米\n", perimeter);
	
	area = height * width;
	printf("矩形的面积 = %d 平方米\n", area);

return(0);
}

The calculation result is as follows:
