Answer:
161 cm
Step-by-step 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:
[tex]\frac{100cm}{1m}=\frac{x}{2m}[/tex] 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.
