Question

A
person jogged 10 times along the perimeter
a rectangular field of zate of 12 kilometer
her hour for 30 min. of field has a length that
is twice its width, the area of the field is.​

Answer 1

The person jogged 10 times along the perimeter of a rectangular field at the rate of 12 kmph and the distance coveted in 30 minutes.

At the rate of 12 kmph the distance covered in 30 minutes is half of 12 km i.e 6 km or 6000 meters.

6000 meters are the 10 times of the perimeter of the field, hence the actual perimeter is..

6000/10 = 600 m. And the length of the field is twice the breadth then the ratio of the Dimentions is 1: 2 and out of the 600 m of the perimeter…

600/3 = 200 m is the breadth and the length is 400 m.

Therefore the Area of the rectangular field in square meters is..

400 X 200 = 80000 or

80000 m² answer.
