Answer 2

Given:

a square carpet of side 3.5cm a rectangular hall 15 m long and 9m wide​

To Find:

Find the area

Solution:

We are given with a square carpet and a rectangular hall and we need to find the area, to find the area of,

Square,

$A=a^2$

where 'a' is the side of the square

Rectangle,

$A=l*b$

where,

          l= length of the rectangle

          b= breadth of the rectangle

Now finding the area by putting the given values we have,

$A_s=3.5*3.5\\=12.25cm^2$

and,

$A_r=15*9\\=135m^2$

Hence, the area of square carpet and rectangle hall is 12.25sq.cm and 135sq.m respectively.
