Answer:
Width = 152 cm
Length = 3040 cm
Step-by-step explanation:
We are given that the length of one flat square shaped slab is 231.04 cm².
Since it is a square, dimension of one side of the flat slab = √231.04 = 15.2 cm
Since there are ten flat slabs, with of the 10 slabs = 10 × 15.2 = 152 cm
Now these slabs are placed across 200 rows to form a walkway.
Thus, length = 200 × 15.2 = 3040 cm
