Question

the perimeter of a rectangle is 60cm.its lenght is twice its width.find its lenght​

Answer 1

Answer:

20

   

Step-by-step explanation:

Let width be x

so length = 2x

as we know perimeter of a rectangle= 2(length+breadth)

so  2(2x+x)=60

     2(3x)= 60

     2* 3x=60

     6x=60

     x=60/6

     x=10

Since x= width

length= 2x

so length= 2*10=20
