Question

A table top measures $2\text{m}$ by $1\text{m 50 cm}$. What is its area in square meters ?

Answer 1

Finding area of the table top :

According to the question, we have to find the rea in square metres.

Here, length is in meter but breadth is not in meter so we convert the bredath into metres.

We know that $1\text{m=100 cm}$

So $50\text{cm=50÷100 =0.5 m}$

Therefore, $1\text{m 50 cm=1+0.5 =1.5 m}$

Now, the units of length and breadth are same and in metres.

We know that,area of recatangle $=\text{length×breadth}$

SO, area of table top $=2\times 1.5=3.0{\text{m}}^2$

Hence, area of the table top in square metres is $3.0{\text{m}}^2$
