If the length of a rectangle is increased by 10 and the breadth decreased by 5 the area is unchanged If the length is decreased by 5 and the breadth increased by 4 even then the area is unchanged?

Suppose the dimwnsions of the rectangle are L and B
Then area = LB.
Now (L+10)*(B-5) = LB so that 10B-5L = 50
and (L-5)*(B+4) = LB so that -5B+4L = 20
Solving these two equations simultaneously, gives L= 30,B = 20

Formula for area of the rectangle?
length*breadth
What is the area of the rectangle when the length and breadth are given?
All you need to do is length x breadth = area
How do you find height when length and breadth are given in rectangle?
A rectangle is a 2-dimensional object. It cannot have length and breadth AND height. If three dimensions are given, then two of them (eg breadth and height) must stand for the same thing.
The breadth of a rectangle is ten less than four times its length. Let x be the length of the rectangle What is the perimeter of the rectangle in terms of x?
breadth = 4x - 10 ie length + breadth = 5x - 10. Perimeter is double this figure ie 10x - 20 or 10(x - 2)
Write a c sharp program to find the area of square?
include<stdio.h> #include<conio.h> void main() { int length, breadth, area ; printf("\n Enter the length & breadth of a Rectangle"); scanf("d",&length,&breadth); area=length*breadth; printf("\n Area of the Rectangle=%d",area); getch(); }
The length of the rectangle is greater than its breadth by 2 cm if the length is increased by 4 cm and the breadth decreased by 3cm the area remain same find the length and breadth of the rectangle?
The width is 18 cm and the length is 20 cm. The new dimensions are 15 by 24. The formula used is if w=width, w (w + 2) = (w - 3) (w + 6).
What is area of rectangle when breadth and width are given?
The breadth of a rectangle is the height.
How do you find the length and breadth if area is known for a rectangle?
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!
What happens to the perimeter when a rectangle is enlarged by a scale factor of 5?
if the length and breadth are increased by 5 times each area becomes 25 times
How can you calculate the perimeter of a rectangle if you know its length and breadth?
Add the length and breadth and then double it.
Formula for area of the rectangle?
length*breadth
What is the breadth of the rectangle when the area and length is given?
Divide the area by the length of the rectangle
What is the area of the rectangle when the length and breadth are given?
All you need to do is length x breadth = area
A rectangle with the area of 24cm2 and the width is 6 what is the length?
If 2 sides of the rectangle are 6cm, then the remaining 2 sides are 4cm. Area = Length x Breadth Breadth = Area / Lenghth 24 = 6 x Breadth Breadth = 24 / 6 = 4
How do you find area and length of a rectangle if perimeter and breadth is given?
2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
Write a C program to find the area and perimeter of you square ii rectangle?
#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"); }
How do you find height when length and breadth are given in rectangle?
A rectangle is a 2-dimensional object. It cannot have length and breadth AND height. If three dimensions are given, then two of them (eg breadth and height) must stand for the same thing.
