PLEASE ANSWER THIS QUESTION FAST . IT IS URGENT . I WILL MARK AS BRAINLIEST . BUT GIVE WITH WHOLE EXPLANATION ​

Answer 1

Answer:

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
