Question

avinash ran at a speed of 8ms^-1along the side of a park.if the park is sqare in shape and he took 2 min 30 sec to cover the perimeter once ,find the area of the park

Answer 1

Time = 2 min 30 sec  = 150 s

Distance ran by Abhilash = Perimeter of the park = Speed * time = 8 * 150 = 1200 m

Perimeter of square = 4a = 1200

One side of the park = 1200/4 = 300

Area of the park = a² = 300² = 9000 m²
