Question

If breadth of a rectangle is one-third of its length and it's area is 27 cm^2 .Then find it's perimeter..​

Answer 1

Answer:

24 cm

Step-by-step explanation:

Let the breadth be x.

Length of rectangle = 3x

According to Question,

3x × x = 27

=> 3x² = 27

=> x² = 27/3

=> x² = 9

=> x = 3

Hence, the breadth is 3 cm and length is 9 cm.

Perimeter = 2 (9+3) cm = 2 (12) cm = 24 cm
