Given :- How many pieces of stone slabs each 18 cm long and 14 cm broad will be required to lay a path 154 cm long and 90 cm wide .?
Solution :-
we know that,
- Area of rectangle = Length * Breadth .
so,
→ Area of path = L * B = (154 * 90) cm².
and ,
→ Area of 1 stone slab = L * B = (18 * 14) cm².
now, Let us assume that, n number of stone slabs are required to lay the path .
then,
→ Number of stone slabs * Area of 1 stone slab = Area of path
→ n * (18 * 14) = (154 * 90)
dividing both sides by 18,
→ n * 14 = 154 * 5
dividing both sides by 14,
→ n = 11 * 5
→ n = 55 (Ans.)
Hence, Total 55 stone slabs are required to lay the path .
