Solution

## The correct option is D 140 m Given: The field is rectangular in shape Length of the field = 20 m Breadth of the field = 15 m When the boy is moving along the boundary, he covers the distance equal to the perimeter of the rectangular field. Perimeter of a rectangle = 2( length + breadth) ⇒ Perimeter of the rectangular field = 2×( 20 m + 15 m ) = 2 × 35 m = 70 m So the boy will cover a distance of 70 m in one round. Hence in two rounds, he will cover 2 × 70 i.e. 140 m.
