Answer 2

Given,

Radius $= 1.4cm$

We have to find the area of a carpet

From the given,

We can consider a carpet in the shape of circle

So, that we have to use circle area formula to find the area

Formula,

Area $= \pi r^{2}$

Here, $r =1.4cm$

Now substitute the given values, we get

$= \frac{22}{7} \times 1.4\times1.4$

$= 22\times0.2\times1.4$

$= 6.16cm^{2}$

Therefore, the area of carpet is $6.16cm^{2}$.
