Answer 2

Answer:

the area =$520 cm^{2}$ and the length=32.248; breadth = 16.124

Step-by-step explanation

given:

area of rectangle= 520 $cm^{2}$ =[length x breadth]

length: twice breadth [2b]

breadth[b]

so,

2b x b =$520 cm^2$

$b^{2}$ = 520

$b^{2}$ = 520/2

$b^{2}$ = 260

b= $\sqrt{260$

= 16.124

the lenght= 2 x b = 32.246

breadth= 16.124
