Answer:
no. of tiles = 800
perimeter of wall = 14 m
Step-by-step explanation:
length of marble tile = 15 cm
breadth of marble tile = 20cm
Area of one tile = 15 × 20 = 300cm^2
length of wall = 4m = 400cm
breadth of wall = 6m = 600cm
area of the wall = 400 × 600
= 240000 cm^2
therefore total no. of tiles = 240000÷300 = 800 tiles
perimeter of wall = 2×(l+b)
= 2×( 4+6) = 14 m
