Question

$the \: length \: of \: rectangle \: is \: twice \: of \: its \: breadth \: if \: its \: perimeter \: is48cm \: find \: the \: dimensions \: of \: the \: rectangle =$

Answer 1

length = 2 breadth

perimeter = 48

2( l + b)= 48

l + b= 24

As l = 2b

2b + b= 24

3b =24

b= 8

So l = 2b = 2(8)= 16

Length = 16

breadth = 8

Answer 2

Hi Mate ! !!

Let the breadth of rectangle be = b

it's Length = 2b

perimeter of rectangle = 2 ( 2b + b ) = 48

3b = 24

b = 8

So, it's breadth is 8cm and it's length is 16cm
