Question

A room is 12.5m long and 8m wide. A square carpet of side 8m is laid on its floor. Find the area of the floor which is not carpeted

Answer 1

the area of the room 12.5*8=100

Answer 2

Answer: Our required area is 36 sq. m.

Step-by-step explanation:

Since we have given that

Length of room = 12.5 m

Width of room = 8 m

We need to find the area of floor which is not carpeted.

So, Area of room is given by

$length\times width\\\\=12.5\times 8\\\\=100\ m^2$

Length of square carpet = 8 m

Area of square carpet is given by

$Side^2=8^2=64\ m^2$

So, Area of floor which is not carpeted is given by

$100-64=36\ m^2$

Hence, our required area is 36 sq. m.
