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

Step-by-step explanation:

area =8100

side ×side =8100

side=90

perimeter=90×4

=360

now,360/24=15 minutes

for 3 compelete rounde time would taken =3×15

=45 minutes

Answer 2

Answer:

Step-by-step explanation:

let s length of each side of the square field

area of the field = 8100m²

⇒s² = 8100m

⇒s²= 90m

distance covered in 1 round =perimeter = 4s ⇒4*90=360

distance covered in 3 round= 360*3=1080

speed of man = 24m/min

now, time taken to covered 3 round

distance/speed=1080/24

=45 min
