Answer:

16cm

Step-by-step explanation:

Let W be width

Width=W

Length=2W

Perimeter=(Length+Width)×2

48=(2W+W)×2

48=6W

W=8cm

Therefore length is 8×2=16cm

Answer:

Step-by-step explanation:

Let the width be x

Length = 2*x = 2x

Perimeter = 48 cm

2*(length + width) = 48

2*(2x +x ) =48

2*3x = 48

6x = 48

x = 48/6

x = 8

Width =  8cm

length = 2 * 8 = 16cm
