Question

12.
A girl uses a worn out ruler to measure the length of a table in her room. She placed the ruler such that
the mark 3.0 cm coincides with one end and the other end coincides with the mark 33.5 cm. The
length of the table is _
cm.
(1) 33.5 cm
(2) 36.5 cm
(3) 33.8 cm
(4) 30.5 cm​

Answer 1

Answer:

36.5 cm

I think bcz

The end of the ruler is 33.5 which is coincided with 3cm so it is 36.5cm.

Answer 2

Answer:

30.5 cm

Step-by-step explanation:

The question is a girl uses a worn out ruler to measure the length of a table in her room. She placed the ruler such that  the mark 3.0 cm coincides with one end and the other end coincides with the mark 33.5 cm. The  length of the table is _

First of all the question is given cm so the answer should be also in cm.

Now, it says that she placed the ruler such that  the mark 3.0 cm coincides with one end and the other end coincides with the mark 33.5 cm

The word 'coincide' means that it occurs at the same time. In terms of Mathematics , the coincident lines are lines that lie upon each other in such a way that when we look at them, they appear to be a single line, instead of double or multiple lines, in simple way we can say that coincide means to subtract.

So, Subtract 33.5- 3.0

Which is 30.5

So the Actual length of the table is 30.5
