Perimeter = (2 lengths) + (2 widths)
1/2 of the perimeter = (length) + (width)
Area = (length) x (width)
So if you're given the area and the perimeter:
-- Look for factor-pairs that multiply to give the area.
-- The right pair of factors is the pair that add to give 1/2 of the perimeter.
Example:
Area = 24
Perimeter = 22
Factor pairs that make 24:
1 x 24
2 x 12
3 x 8
4 x 6
Which pair is it ?
Perimeter = 22
1/2 the perimeter = 11.
Look at the sums:
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11 <===
4 + 6 = 10
The rectangle is 3 by 8 .
Add the length and breadth and then double it.
#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"); }
No, you do not divide the perimeter by the length to find the breadth. Instead, for a rectangle, you can use the formula for the perimeter, which is ( P = 2 \times (length + breadth) ). To find the breadth, you can rearrange the formula to solve for breadth: ( breadth = \frac{P}{2} - length ).
Area is length times width, perimeter is twice the sum of length and breadth.

Add the length and breadth and then double it.
perimeter of rectangle=2(l+b) l=length of the rectangle b=breadth of the rectangle
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"); }
Well, isn't that just a happy little problem to solve! To find the area of a rectangle, you multiply the length by the breadth. And to find the length, you can use the formula: length = (perimeter - 2 * breadth) / 2. Just remember, there are no mistakes, only happy accidents in math!
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56
No, you do not divide the perimeter by the length to find the breadth. Instead, for a rectangle, you can use the formula for the perimeter, which is ( P = 2 \times (length + breadth) ). To find the breadth, you can rearrange the formula to solve for breadth: ( breadth = \frac{P}{2} - length ).
Area is length times width, perimeter is twice the sum of length and breadth.
breadth = 4x - 10 ie length + breadth = 5x - 10. Perimeter is double this figure ie 10x - 20 or 10(x - 2)
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
Perimeter of a rectangle = 2(length + breadth) if one of it's side is doubled then, the resultant perimeter will be 2(2length + breadth) or 2(length + 2 breadth) as the case may be.
Perimeter = 2*(Length + Breadth) So, 1570 = 2*(168 + Breadth) 785 = 168 + Breadth Breadth = 617 metres Which is rather an unusual result because normally the length is greater than the breadth.
