Question

if the length of a rectangle is double to its breadth and area is 800 CM square then the perimeter is​

Answer 1

this is the answer of your question

Answer 2

Let the breadth be x

So, the length is 2x

A/Q

Area of rectangle =l*b

800 =x*2x

800 =2xsquare

800/2=xsquare

400=xsquare

$\sqrt{400} = x$

20=x

X=20

L=2x

=2*20

=40

B=20
