you have to convert min into hr
that is 3/60=1/20
speed =distance/ time
distance=speed*time
=3*1/20=3/20
let the square of side a
diaginla length of square =a√2
a√2=3/20
by solving you get value of a
after finding value of a you easily find area of square.

The speed of the man is 3kmph that means it walk 3000m in 60m and 50 m in one minute
According to que he is walking 3min so the diagonal of the square field is 50×3 =150m
Now area of sq field=1/2×(diagonal )^2
Area = 1/2×22500
Area = 11250m^2
Hence the area of the field is 11250m^2.
