Pls write the correct answer. Correct answer will be marked as brainiest and spams will be reported. Thank you for answering my question in advance.

Answer 1

Area of square playground = a²

a² = 256.6404

a = √256.64

a = 16 m ( approx.)

so,

the perimeter of playground = 4a

perimeter = 4×16

perimeter = 64m²

it means that , the men covers 64m² distance at the speed of 6km/ hr.

→ time taken by the men to cover 64m² = ???

→ speed in m/s = 6× 5 ÷ 18

→ speed = 1.6 m/s

→ speed = distance ÷ time

→ 1.6 = 64 ÷ t

→ t = 64 × 1.6

→ t = 102.4 sec.

TIME TAKEN FOR FIVE REVOLUTION.. = t × 5

→ 102.4 × 5

→ 512 sec...
