Answer:
24 Marble Slabs
Step-by-step explanation:
Floor Area = 9 m²
A Marble slab measures 75cm in length & 50 cm in breadth
Marble Slab length = 75 cm = 75/100 m ( 1cm = 1/100 m)
Length = 3/4 m
Marble Slab Breadth = 50 cm = 50/100 m = 1/2 m
Area of a marble slab = Length * Breadth
= (3/4) * (1/2)
= 3/8 m^2
Number of Marble slabs required = (Floor Area)/(Marble Slab Area)
Number of Marble slabs required = 9/ (3/8)
= 3 * 8
= 24 Marble Slabs
