Question

1. Arya took 4 rounds around a rectangular field
130 m long and 110 m wide. How many
kilometres did she walk?
Solution :​

Answer 1

Length of rectangle given = 130m

Breadth given = 110m

As it is given in the statement that she is moving on the boundary of field, we need to find the perimeter ;

So, Perimeter of a rectangle = 2(length+breadth)

So, 2(130+110)

= 2(240) = 480m

Now,distance travelled by her = 480×4 = 1920m

For converting in kms = (1 m =1/ 1000Km)

So, 1920m = 1920/1000 = 1.920 Km Answer.

Hence, She walked 1.920 Kilometres.

HAVE A NICE DAY!

Answer 2

Step-by-step explanation:

First we have to find the perimeter of the rectangular field.

The perimeter of the field = 2(l + b)

2(130 + 110)

2× 240

480 m

Arya took 4 rounds of the field...

So,kilometers she walked is = 480 × 4

= 1920 m or 1.920 km
