Answer:

Her drawing is 15 cm

Step-by-step explanation:

First we need to figure out how tall the object is.  We can use proportions.  Put drawing size over real life

1 cm         12 cm

------- = -----------

5 ft          x ft

Using cross products

1*x = 12*5

x = 60 ft

In real life the statue is 60 ft

Now when Kia draws it  1 cm =4ft  to xcm to 60 ft

1 cm         x cm

------- = -----------

4 ft          60 ft

Using cross products

1*60 = 4x

60 =4x

Divide by 4

60/4 = 4x/4

15 =x

Her drawing is 15 cm
