Question

1. The ratio of the length and breadth of a rectangle is 5:4. If the length is 25 m, the breadth is
(2) 20 m
(3) 10 m
(4) 12 m
(1) 15 m
​

Answer 1

Answer:

Breadth = 20m

Step-by-step explanation:

Let the length be 5 x and breadth be 4 x

Length = 25m

=> x = 5

So ,

=> 25 / b = 5 / 4

=> b = 20 m

Answer 2

Given :

• Ratio of Length and Breadth of a Rectangle is 5:4 .
• Length is 25 m .

To Find :

• Breadth of Rectangle .

Solution :

$\longmapsto\tt{Let\:Length\:of\:Rectangle\:be=5x}$

$\longmapsto\tt{Let\:Breadth\:of\:Rectangle\:be=4x}$

Now ,

As Given that Length is 25 m . So ,

$\longmapsto\tt{5x=25}$

$\longmapsto\tt{x=\cancel\dfrac{25}{5}}$

$\longmapsto\tt\bf{x=5}$

Value of x is 5 ..

Therefore :

$\longmapsto\tt{Breadth\:of\:Rectangle=4(5)}$

$\longmapsto\tt\bf{20\:m}$

_______________________

• Area of Rectangle = length × breadth
• Perimeter of Rectangle = 2(l+b)
• Diagonal of Rectangle = √(l)² + (b)²
• Area of Square = (Side)²
• Perimeter of Square = 4 × Side
• Diagonal of Square = √2a
