Question

The perimeter of a rectangle is 24m. and its breadth and length are in the ratio 3:5.What are the breadth and length?​

Answer 1

let's it breadth and length respectively be 3x and 5x

by substituting general method to find perimeter in rectangle that is 2(l+b)

2(3x+5x)=24

8x=12

x=1.5

Answer 2

☆ Solution ☆

Given :-

• The perimeter of a rectangle is 24m.
• The breadth and length are in the ratio 3:5.

To Find :-

• Breadth of rectangle
• Length of rectangle

Step-by-Step-Explaination :-

Let the ratios be 3x and 5x

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Where,

• Perimeter of rectangle = 24 m

• Breadth of rectangle = 3x

• Length of rectangle = 5x

Putting the respective value,

24 = 2 ( 3x + 5x )

12 = 8x

x = 12/8

x = 1.5

Thus,

The breadth of rectangle = 3x = 3 × 1.5 = 4.5 m

The length of rectangle = 5x = 5 × 1.5 = 7.5 m

Hence Solved !
