Answer:

x = 5 cm

Step-by-step explanation:

Big rectangle

Length = 30 cm

Width = 12.5 cm

Length : width = 30 cm : 12.5 cm

Small rectangle

Length = 12 cm

Width = x cm

Length : width = 12 cm : x cm

Equate the ratios

30 cm : 12.5 cm = 12 cm : x cm

30/12.5 = 12/x

Cross product

30 * x = 12.5 * 12

30x = 150

x = 150/30

x = 5 cm
