Question

the Length and width of a rectangle is in ratio 3:5if it is perimeter is 48 cm find its length ​

Answer 1

Step-by-step explanation:

let the length of the rectangle be 3x

and breadth = 5x

perimeter of rectangle = 2(l + b)

= 2 ( 3x + 5x ) = 48

= 2 ( 8x ) = 48

16x = 48

x = 48/16

= x = 3

so length of the rectangle = 3x

= 3 × 3

= 9cm.

.....

Answer 2

Answer:  9 cm

Step-by-step explanation:

Let the length be 3x and breadth be 5x

Thus ,  perimeter of a rectangle = 2(l+b) = 48cm

                                                       = 2(8x) = 48cm

                                                       =  x = 48/16 = 3cm

The length of the rectangle = 3*3 cm = 9 cm
