Final answer:
The total distance covered by Sita is D = s × ( perimeter of rectangle ):
D = s x 710 m.
Step-by-step explanation:
The question asks us to find the total distance covered by Sita when she takes round 's' of a rectangular park with given length and breadth.
To calculate the perimeter, which is the distance Sita covers in one round, we add together twice the length and twice the breadth of the rectangle.
The formula to find the perimeter (P) of a rectangle is:
P = 2 × (length + breadth)
For a park of 250 m length and 105 m breadth, the perimeter would be:
P = 2 × (250 m + 105 m)
= 2 × 355 m
= 710 m
If Sita takes 's' rounds, the total distance (D) she covers would be:
D = s × perimeter
D = s x 710 m.
Replacing 's' with the specific number of rounds Sita takes, we can find the total distance covered by her.
