Question

Rectangular park has a walking trail on its periphery. If the length of the park is 47 metre and the breadth is 30 metre, then find the distance that a person will cover if he takes 3 complete round(s) of the park. a) 420m b)410m c)462m d)452m

Answer 1

The total distance covered after 3 complete rounds of the park, with a length of 47 meters and a breadth of 30 meters, is calculated using the perimeter formula, resulting in 462 meters.

Step-by-step explanation:

To calculate the distance that a person will cover if they take 3 complete rounds of the park, we need to use the formula for the perimeter of a rectangle, which is P = 2(length + breadth). Given the length of the park is 47 meters and the breadth is 30 meters, the perimeter of the park would be:

P = 2(47m + 30m) = 2(77m) = 154m.

Therefore, if a person takes 3 complete rounds of the park, the total distance covered would be:

Total Distance = Number of rounds × Perimeter of the park = 3 × 154m = 462m.

Hence, the correct answer is (c) 462m.

Answer 2

c)462m

Step-by-step explanation:

If a person walks round the park, the person would be walking the whole perimeter of the trail

Perimeter = 2 x (length + breadth)

2 x (30m + 47m) = 154m

If he walks three times, the distance covered = 154m x 3 = 462m
