Perimeter of the rectangle:
The perimeter of a rectangle is given by the formula: P = 2l + 2b, where l is the length and b is the breadth of the rectangle. Given the length (l) as 80m and the breadth (b) as 35m, we can substitute these values in the formula to find the perimeter:
P = 2(80) + 2(35)
P = 160 + 70
P = 230m
Distance covered in one round:
Since the rectangle has four sides of equal length, the distance covered in one round is equal to the perimeter of the rectangle. In this case, the distance covered in one round is 230m.
Distance covered in three rounds:
To find the distance covered in three rounds, we multiply the distance covered in one round by three:
Distance covered in three rounds = 230m × 3 = 690m
Time taken to cover the distance:
The boy's speed is given as 1.5m per second. We can use the formula: Time = Distance / Speed, to find the time taken to cover the distance:
Time = 690m / 1.5m/s
Time = 460 seconds
Therefore, the boy will take 460 seconds to go three times round the field.

Distance covered in three rounds:
To find the distance covered in three rounds, we multiply the distance covered in one round by three:
Distance covered in three rounds = 230m × 3 = 690m
Time taken to cover the distance:
The boy's speed is given as 1.5m per second. We can use the formula: Time = Distance / Speed, to find the time taken to cover the distance:
Time = 690m / 1.5m/s
Time = 460 seconds
Therefore, the boy will take 460 seconds to go three times round the field.

Length = 80m
Breadth = 35m
Perimeter= 2(l+b) = 2 × 115 = 230m
230 × 3 = 690m
the boy moves at a rate 1.5m per second.
Speed = Distance/ Time
Time = Distance/Speed= 690÷1.5= 460 sec
460s = 7 min 40 sec
Breadth = 35m
Perimeter= 2(l+b) = 2 × 115 = 230m
230 × 3 = 690m
the boy moves at a rate 1.5m per second.
Speed = Distance/ Time
Time = Distance/Speed= 690÷1.5= 460 sec
460s = 7 min 40 sec
