Question

table top measures 3M by 50 cm the area in square metre will be​

Answer 1

length=3m

width=5cm/100

=0.05m

area=length*width

=3m*0.05m

=0.15m²

Answer 2

Answer:

Hence the area of top of a table is $1.5\;m^{2} .$

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The measures of top of a table are 3 m by 50m i.e. length (l) is 3 m and width (w) is 50 cm.

We have to find the area of top of a table (A).

At first, we will convert 50 cm in m.

We know that,

$1\;cm=0.01\;m$

So we will multiply 50 by 0.01 we get 0.5 m.

$=50\times0.01\\=0.5\;m$

Now we will be using the formula of area of rectangle.

$A=l\times b$

We will substitute the value of l and b in above formula.

$A=3\times0.5$

Now we will multiply above values,

$A=1.5\;m^{2}$

Hence the area of top of a table is $1.5\;m^{2} .$
