( With solution) please write solution​

Answer 1

Step-by-step explanation:

AREA OF A TILE= LENGTH×BREADTH =12×10 =120cm^2

AREA OF RECTANGULAR REGION= 440×300=132000cm^2

NUMBER OF TILES REQUIRED IS:-

AREA OF RECTANGULAR REGION/AREA OF A TILE

=132000/120 =11,000

Answer 2

Answer:

area of the marble

length=12

breath=10

area of the marble is equal to( length* breadth)

12*10=120

area of the rectangular region

long=440cm

wide=300cm

area of the rectangular region(a*b)

440*300=132000cm

area of the rectangle region divided area of the marble

132000/120=11000 tiles

therefore 11000 tiles needed to cover the rectangular region
