Question

14. The length of a rectangle is twice of its breadth. If its perimeter is 60 cm, find its length

​

Answer 1

this is the answer.......

Answer 2

Answer:

ans. 10 & 20.

Step-by-step explanation:

Let the breadth of the rectangle = x

therefore, according to question,

length of rectangle = 2x.

Now, perimeter of rectangle = 60 = 2 (l+b)

=> 60 = 2 (2x+x)

=> 60 = 2 (3x)

=> 60 = 6x

or x = 60/6 = 10...

Therefore, Breadth of rectangle = 10cm.

& length of rectangle = 2(10) = 20cm..
