A rectangular ground is 40 m long and 30 m board . If a girl runs three times around the ground , what distance does she covers?

length = 40 m

breadth = 30m

Perimeter = ?

Now ,

Perimeter = 2 (l+b)

= 2 ( 40 + 30 m )

= 2 × 70 m

= 140 m

Now ,

If a girl runs three time around the ground =140 m×3

= 420m

The answer is 420 meters.

Step-by-step explanation:

40 + 40 + 30 + 30 = 140

140 * 3 = 420
