Question

The ratio of the length of a rectangle to its breadth is
3:2. If its perimeter is 130 m, find its length and breadth.

Answer 1

Answer:

length = 3x = 39 m

breadth = 2x = 26 m

Step-by-step explanation:

let the length and breadth be 3x and 2x

perimeter of a rectangle = 2(l+b)

                                 130 = 2 (3x + 2x)

                                 130 = 2 (5x)

                                  5x = 130/2

                                   5x = 65

                                     x = 65 / 5 = 13

Answer 2

Step-by-step explanation:
* Question
The ratio of the length of a rectangle to its breadth is 3:2. If its perimeter is 130m,
find its length and breadth.
Given :
Perimeter = 130 m
Length = 3x
Breadth = 2x
* To find :
The value of length and breadth.
* Solution :
Perimeter of rectangle = 2(1+b)
- 130m = 2(3x+2x)
> 130m = 2(5x)
> 130m = 10X
> 10x = 130m
=× = 130/10
+ X = 13
Now, By putting the value of 'x' as 13, We have:-
Length = 3x
=> 3× 13
=> 39
Therefore, The length of the rectangle is 39m.
Breadth = 2x
=> 2×13
> 26m
Therefore, The breadth of the rectangle is 26m.
