That is how the concept of area is defined!
length * breadth. (or, can be said as - length times width)
If the breadth of the rectangle is 2, then its length is 5. which means that the area is 10 square units.
When the breadth of a rectangle is doubled, the area of the rectangle also doubles. The area of a rectangle is calculated by multiplying its length by its breadth (Area = Length × Breadth). Therefore, if the original breadth is increased to twice its size, the new area becomes Area = Length × (2 × Breadth), resulting in double the original area.
Area is length times width, perimeter is twice the sum of length and breadth.
#include<stdio.h> void main() { float length, breadth, area, perimeter; printf("Enter the length & breadth of a Rectangle\n(length breadth): "); scanf("%f %f",&length,&breadth); area=length*breadth; perimeter=2*(length+breadth); printf(" Area of the Rectangle=%0.3f\n",area); printf("Perimeter of the Rectangle=%0.3f\n",perimeter); printf("(Press ENTER to exit.)"); getch(); printf("\n"); }

If you do not know the length or breadth of a rectangle, you cannot know the area. If you do not know the area of a rectangle, you cannot know the length and breadth. To know the length and breadth of a rectangle, you have to know some other contributing factor in the equation. If you don't, measure it!
Area is length times width, perimeter is twice the sum of length and breadth.
Divide the area by the length of the rectangle
All you need to do is length x breadth = area
length*breadth
#include<stdio.h> void main() { float length, breadth, area, perimeter; printf("Enter the length & breadth of a Rectangle\n(length breadth): "); scanf("%f %f",&length,&breadth); area=length*breadth; perimeter=2*(length+breadth); printf(" Area of the Rectangle=%0.3f\n",area); printf("Perimeter of the Rectangle=%0.3f\n",perimeter); printf("(Press ENTER to exit.)"); getch(); printf("\n"); }
If the breadth is 3, it means that the length is 5 which therefore means the area is 15 square units.
Area of rectangle = length * breadth
Area of rectangle = length * breadth or length * width
