Question

A rectangular hall is of length 60 m and breadth 40 m.
What is the maximum number of square granite slabs, each of side length 7 m, that can be placed along
the length of the hall (in one row)?​

Answer 1

Step-by-step explanation:

Given,

Length of rectangular hall = 60m

Breadth of rectangular hall = 40m

Area of rectangular hall = lb = 60m × 40m = 2400m²

Side of 1 square granite slab = 7m

Area of 1 square granite slab = s² = 7² = 49m²

Number of square granite slabs = 2400/49 = 48.979 = 49 (approximately)
