Question

The length & breadth of a rectangular playground are 125m and 62m respectively. What distance will a boy cover in walking around the playground four times.

Answer 1

the answer is 4 x ( perimeter of the playground)
= 4 x 2(l+b)
=8(125+62)
=1496m.

Answer 2

Length of playground = 125 m

Width of playground = 62 m

Perimeter of playground = 2 (Length + Width)

= 2 ( 125 + 62)

= 2 ( 187)

= 374 m

Distance covered = 4 × Perimeter of playground

= 4 × 374

= 1496 m

= 1.496 km
