Question

The area of a square field is 10000sq meters . Mridul takes 4 rounds of this field along its boundary . If he walks at 50m/minute , how much time will he require to do It?

Answer 1

Area if square = 10000 msq

Area of square = AxA = A^2

A^2 = 10000

A = 100

so side of square = 100

perimeter = 4A = 400 m

he walks 50m/min

time required to traverse 1 round of square field = 400/50 = 8 mins

time required to traverse 4 rounds = 8x4 = 32 mins

Answer 2

Answer:

the right answer is 32 minutes.
