Answer 2

Answer :

3. No, this is not a sensible estimate.

Because most of the buildings are built double the height of the average human. 2meter are equal to just 6.5 feet. But if the height of the kitchen is 2m then the person with 6feet height cannot adopt to this, it seems to be very small when compared to average height of any rooms which are used by people.

Therefore it is not a sensible stimate

Answer:

4.

The estimated height of the lamppost is $33.6$ m

Given: Anna is 1.6m tall

She estimated that the lamppost is 21 times as tall as she is

To find: The height of the lamppost

Solution:

Let x be the height of the lamppost

The height of Anna $= 1.6$

Estimated height of the lamppost $= 21$ ×$1.6$

                                                          $= 33.6$ m

Therefore, the estimated height of the lamppost is $33.6$ m
