First, we need to convert the boy's speed from kilometers per hour (km/hr) to meters per second (m/s), which is the standard unit of speed for measuring distances in meters. To do this, we can use the conversion factor 1 km/hr = 1000 m/3600 s. 9 km/hr = (9 * 1000) / 3600 m/s ≈ 2.5 m/s (rounded to one decimal place) The distance around the square field is the perimeter, which is four times the length of one side: Perimeter = 4 × side length = 4 × 35 m = 140 m The time it takes the boy to run around the field is the distance divided by his speed: Time = Distance / Speed = 140 m / 2.5 m/s = 56 s Therefore, the boy will take 56 seconds to run around the square field of side 35 meters at a speed of 9 km/hr.

Let the breadth of the rectangle be x metres
and the length is 2x metres.
So, area of rectangle is 800 sq.m.
(x)(2x) = 800
2x²= 800
x²= 400
x = {tex}\pm{/tex} 20
But breadth of rectangle cannot be negative, so x = 20
and yes, it is possible to design it.
So, Breadth is 20 m and length is 40 m.

Kalam used to wear a cap and Ramanandha Sastry wore a sacred thread which marked him to be a Brahmin. When the new teacher came he could not tolerate a Hindu priest’s son sitting with a Muslim boy. He ordered Kalam to go and sit on the backbench. This made Ramanandha sad. Abdul started to sit in the last row but it left a bad impression on Abdul. Both the kids narrated the incident to their parents. As a result, the teacher was rebuked and reprimanded for spreading communalism and hatred among children
