Question

0. Saroj and Kavita like to keep themselves physically fit. They jog daily in the morning. Saroj jogs

around a rectangular park of dimensions (xy + y2) m and (xy - yz) m. Kavita jogs around a square
park of side (2x + 3y) m.
a. What distance does Saroj cover in 5 rounds?
b. What distance does Kavita cover in 1 round?

Answer 1

To find the distances covered by Saroj and Kavita, one must calculate the perimeters of the rectangular park (for Saroj) and the square park (for Kavita) and then multiply by the number of rounds they complete.

Step-by-step explanation:

The student is asking two separate questions involving physical fitness and geometry. The distance Saroj covers in 5 rounds around a rectangular park and the distance Kavita covers in 1 round around a square park can be found using the perimeter formulas for rectangles and squares respectively.

For Saroj, the distance covered in one round is twice the sum of the lengths of two adjacent sides of the rectangle:

• Distance for 1 round = 2 × ((xy + y2) + (xy - yz)) m
• Distance for 5 rounds = 5 × 2 × ((xy + y2) + (xy - yz)) m

For Kavita, the distance covered in one round is the perimeter of the square:

• Distance for 1 round = 4 × (2x + 3y) m
