Question

the area of a sheet of length 10.2 cm and width 6.8 cm addressed upto proper number of significant figures is?

Answer 1

Answer : Area, $A=69.4\ cm^2$

Explanation :

It is given that,

The length of the sheet is l = 10.2 cm

The width of the sheet is b = 6.8 cm

The sheet is in the form of rectangle.

We know that the area of the sheet is :

$A=l\times b$

$A=10.2\ cm\times 6.8\ cm$

$A=69.36\ cm^2$

or

$A=69.4\ cm^2$

Hence, this is the required solution.
