Answer 2

Given:

Height of a person=1.45m

To find:

The height of the person in cm and mm.

Solution:

The height of the person is 145 cm and 1,450 mm.

We can find the height by following the given steps-

We know that to express the height in cm and mm, we need to convert height from m.

i. Height of the person in cm.

We know that 1 meter=100 centimeter

The height of the person=1.45m

To convert it to cm, we need to multiply it by 100.

So, the height of the person expressed in cm=1.45×100

=145×100/100

=145cm

ii. Height of the person in mm.

We know that 1 meter=1000 millimeter

The height of the person=1.45m

To convert it to mm, we need to multiply it by 1000.

So, the height of the person expressed in mm=1.45×1000

=145×1000/100

=145×10

=1,450mm

Therefore, the height of the person is 145 cm and 1,450 mm.
