Answer:

161 cm

Explanation:

The door opening is 2 meters high, so to compare the gap and Casey's height, you need to first convert the meters to centimeters. Since there are 100 centimeters in 1 meter:


(100cm)/(1m)=(x)/(2m) where 'x' is the number of centimeters

100(2) = x or x = 200 cm

From the total height of the door (200cm), there is a 29 cm gap to the top of Casey's head:

200 - 39 = 161cm, so Casey must be 161 cm tall.
