Question

Find the distance travelled by Rama if she takes two rounds of a rectangular park whose length is 8 km and breadth is 12 km.​

Answer 1

80 km

Explanation:

First, find the perimeter of the park.

2(12 + 8) = 2(20) = 40 km

Since Rama travels around the park twice, multiply the perimeter by 2.

40(2) = 80 km

Answer 2

9514 1404 393

Answer:

80 km

Explanation:

The perimeter is twice the sum of length and breadth:

P = 2(length +breadth)

P = 2(8 km +12 km) = 40 km

Twice around is then ...

2 × 40 km = 80 km . . . . distance traveled by Rama
