Answer 1

Answer:

let the breadth be x

length =2x

Step-by-step explanation:

the perimeter of the rectangle=2(l+b)

=2(2x+x)

=2(3x)

6x

Answer 2

perimeter of rectangle is 18cm

breadth of rectangle is x cm

length of rectangle is 2x cm

perimeter of rectangle is 2(l+b)

18cm =2(x+2x)

18cm=2(3x)

18cm = 6x

x is 3cm

length is 6cm

breadth is 3 cm
