Question

Ravi has to take a walk around a field once. If the field is 15 m long and 20 m wide, then how many metres does he have to walk?

Answer 1

Ravi has to walk 70 meters around the field.

Step-by-step explanation:

To find the distance Ravi has to walk around the field, we need to calculate the perimeter of the field. The perimeter of a rectangle is given by the formula: P = 2L + 2W, where L is the length and W is the width of the rectangle.

Substituting the given values, we get: P = 2(15m) + 2(20m) = 30m + 40m = 70m.

Therefore, Ravi has to walk 70 meters around the field.

Answer 2

Answer: 70 m

Step-by-step explanation:

The field described has the shape of a rectangle because one side is longer than the other.

The length that Ravi would have to walk therefore is the perimeter of this rectangle.

Perimeter = 2 × ( Length + Width)

= 2 × ( 15 + 20)

= 2 × 35

= 70 m
