Question

area of a rectangular field is 3584 m² and the length and the breadth are in the ratio 7:2, respectively. what is the perimeter of the rectangle?​

Answer 1

Step-by-step explanation:

$perimeter = 288 \: m$

Answer 2

Answer:

4608cm square

Step-by-step explanation:

The given area of the rectangle=3584

The given ration =7:2

so length=7x

breadth=2x respectively

AREA OF RECTANGLE=Length X Breadth

                                      =7x X 2x

                                      =14x

so accordingly,

3584=14x

x=3584/14

x=256

so length= 7x

               =7[256]=1792

so breadth=2x

                 =2[256]=512

PERIMETER OF RECTANGLE=2[L+B]

                                               =2[1792+512]

                                               =2[2304]

                                               =4608cm
