Question

The Perimeter of a rectangle is 36cm What
is the breadth If the length is twice the breadth ____​

Answer 1

Answer:

the breadth = x and the length =2x  

perimeter = 2 (l+b)  

36 = 2 ( x + 2x )    

36/2 = (x+2x)

18 = 3x    

18/3 = x  

6 = x  

The breadth is 6 cm and length will be 12 cm.

Answer 2

Answer:

let, breath is x

then length will 2x

it's perimeter is 36

formula of perimeter of rectangle is 2(l+b)

2(x+2x)=36

2x+4x=36

6x=36

x=6

breath =6
