Answers
The number of slaves required to cover the floor is 504 and if each slab cost rupees 4, then the cost of the slabs is Rs. 2016.
Step-by-step explanation:
The dimension of the floor of the hall:
Length, l = 7.2 m
Width, w = 6.3 m
∴ The area of the floor of the hall = l × b = 7.2 × 6.3 = 45.36 m²
The dimension of each square slab:
Side = 30 cm = 0.3 m
∴ Area of each square slab = side² = 0.3² = 0.09 m²
Therefore,
The no. of slabs required to cover the floor of the hall is,
= [Area of the floor of the hall ] / [Area of each square slab]
= 45.36 / 0.09
= 504
Now,
The cost of each slab is given as Rs. 4
∴ The cost of 504 slabs will be = Rs. 4 × 504 = Rs. 2016
