PLS MARK AS THE BRAINLIEST

Step-by-step explanation:

LENGTH OF  THE FLOOR=4M

BREADTH OF THE FLOOR=5M

∴AREA OF THE FLOOR=(4×5)M^2=20M^2

EACH SIDE OF A SQUARE TILE=0.4 M

∴AREA OF THE SQUARE TILE=(0.4×0.4)M^2=0.16M^2

∴NO. OF TILES REQUIRED=20M^2 ÷0.16M^2=    75

COST 0F 1 TILE=RS. 9

∴COST OF 75 TILES= RS. 75×9 = RS. 675
