2. The height of the kid is 2 m 30 cm. What is the height of the teacher if the height of the teacher is three times the height of the kid?

a) 6 m 60 cm
b) 6 m 90 cm
c) 9 m 60 cm
d) 9 m 90 cm

Answer: b) 6 m 90 cm

Explanation: Height of the kid = 2 m 30 cm

= 2 m + 30 cm
= (2 x 100) cm + 30 cm
= 200 cm + 30 cm
= 230 cm 

The height of the teacher is three times the height of the kid.

Height of the teacher = 3 x Height of the kid
= 3 x 230 cm = 690 cm
= 600 cm + 90 cm
= 6 m + 90 cm
= 6 m 90 cm
