Question

the area of a square feild is 8100 square metres . a man walks along the boundary at 24m/min . in how much time will he complete three rounds of the feild ... plss ans.​

Answer 1

Answer:

Area of square field=8100

let a be the side of the square,

so a²=8100

so a=90= side of a square

total perimeter of square=4x90=360

To complete 3 rounds of the field of perimeter 360 he has to travel (3x360)m

but he travels 24m in 1 min.

therefore he takes, time=3x360/24 min

=45 min.
