Usually, yes.
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!
Add the length and breadth and then double it.
Divide the area by the length of the rectangle
2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
All you need to do is length x breadth = area
length*breadth
If the shape is a rectangle (or square), then Perimeter = 2*(Length + Breadth) So Breadth = Perimeter/2 - Length
#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"); }
This length (diagonal) = sq.rt ( l2 + b2 ) where 'l' is length of the rectangle and 'b' is the breadth of the rectangle.
length * breadth. (or, can be said as - length times width)
breadth multipied by the length
