Question

the area of a square is 1094 meter square find the time taken by a man to make 5 rounds of the field working at a speed of 4.5 km per hour

Answer 1

Since area of square is a *2 so a*2=1094 so a=33.07. now the perimeter =4a =4(33.07)
=132.302. Since as we know the man rounds 5 time so 5(132.302)=661.51
As we know that time =distance /speed
=661.51/4.5=147.002ans
Hence time taken =147.002sec
