Question

A ROOM IS 12.5 LONG AND 8M WIDE .A SQUARE CARPET PF 8M IS LAID ON ITS FLOOR .FIND THE AREA OF FLOOR WHICH IS NOT CARPETED​

Answer 1

Step-by-step explanation:

Given, length (long) of the room is 12.5m

and breadth(wide) is 8m. The side of square carpet is 8m.

solution:

Let's find the area of rectangular floor. formula for finding the area of rectangle is l×b

so, area of rectangle is =12.5×8=100sq.m

now the area of square is side square

therefore the area of the square is =8×8=64sq.m

area of floor not carpeted

=area of rectangle-area of square

= 100-64

=36sq. m

therefore the area of the floor not carpeted is 36 sq. m
