Answer 2

Answer:

98cm square is the answer

Step-by-step explanation:

let the breadth be x cm

so length will be 2x cm

perimeter=42cm

formula of perimeter of rectangle is 2(l+b) where l is for length and b is for breadth

so according to the question

2(2x+x)=42

x=7 cm

so length=7*2cm=14 cm

breadth=7 cm

area of rectangle =l*b

14*7=98cm square
