Answer 2

drawing length = 7 cm; actual length = 200 cm

Explanation:

The ratio is 1 cm in the drawing is 30 cm in actuality.

If the drawing is 5 cm, multiply by 5

5*1 to get the 5 cm drawing and 5*30 to 150 cm in actual length

5cm drawing = 150 cm actual

11cm drawing multiply by 11

11*1= 11 and 11*30 = 330 cm

11 cm drawing = 330 cm actual

7cm drawing multiply by 7

7*1= 7 and 7*30 = 210 cm

7 cm drawing = 210 cm actual

8cm drawing multiply by 8

The one that is not correct: drawing length = 7 cm; actual length = 200 cm

8*1= 8 and 8*30 = 240 cm

8 cm drawing = 240 cm actual
